80-510: In 1996, FYI Software, founded by Geoff Perlman, bought CrossBasic, which had been marketed by its author Andrew Barry as a shareware product. CrossBasic got its name from its ability to compile the same programming code for the classic Mac OS and the Java virtual machine (although the integrated development environment was Mac only). A public beta was released in April 1996. The CrossBasic name

160-549: A numeric character reference . Consider the Chinese character "中", whose numeric code in Unicode is hexadecimal 4E2D, or decimal 20,013. A user whose keyboard offers no method for entering this character could still insert it in an XML document encoded either as &#20013; or &#x4e2d; . Similarly, the string "I <3 Jörg" could be encoded for inclusion in an XML document as I &lt;3 J&#xF6;rg . &#0;

240-412: A certain level representing the end of the trial period. Racks of games on single 5 1/4-inch and later 3.5-inch floppy disks were common in retail stores. However, computer shows and bulletin board systems (BBS) such as Software Creations BBS were the primary distributors of low-cost software. Free software from a BBS was the motivating force for consumers to purchase a computer equipped with

320-414: A license required for use in a business enterprise. The software itself may be time-limited, or it may remind the user that payment would be appreciated. Trialware or demoware is a program that limits the time that it can be effectively used, commonly via a built-in time limit, number of uses, or only allowing progression up to a certain point (e.g. in video games, see Game demo ). The user can try out

400-448: A list of syntax rules provided in the specification. Some key points in the fairly lengthy list include: The definition of an XML document excludes texts that contain violations of well-formedness rules; they are simply not XML. An XML processor that encounters such a violation is required to report such errors and to cease normal processing. This policy, occasionally referred to as " draconian error handling", stands in notable contrast to

480-589: A long time. An example for emailware is the video game Jump 'n Bump . Another popular postcardware company is the Laravel package developers from Spatie, which has released over 200 open-source packages to the Laravel framework , which are postcardware licensed, and all shown at their website. In 1982, Andrew Fluegelman created a program for the IBM PC called PC-Talk , a telecommunications program, and used

560-456: A longer version of the game, and in other cases the later episodes would be stand-alone games. Sometimes the additional content was completely integrated with the unregistered game, such as in Ambrosia's Escape Velocity series, in which a character representing the developer's pet parrot , equipped with an undefeatable ship, would periodically harass and destroy the player after they reached

640-522: A mechanism whereby an XML processor can reliably, without any prior knowledge, determine which encoding is being used. Encodings other than UTF-8 and UTF-16 are not necessarily recognized by every XML parser (and in some cases not even UTF-16, even though the standard mandates it to also be recognized). XML provides escape facilities for including characters that are problematic to include directly. For example: There are five predefined entities : All permitted Unicode characters may be represented with

720-410: A message when the user starts the program, or intermittently while the user is using the application. These messages can appear as windows obscuring part of the screen, or as message boxes that can quickly be closed. Some nagware keeps the message up for a certain time period, forcing the user to wait to continue to use the program. Unlicensed programs that support printing may superimpose a watermark on

800-491: A modem, so as to acquire software at no cost. The success of shareware games, including id Software hits Commander Keen and Doom , depended in part on the BBS community's willingness to redistribute them from one BBS to another across North America. The reasons for redistribution included allowing modem users who could not afford long-distance calls the opportunity to view the games. The important distinguishing feature between

880-555: A more compact non-XML syntax; the two syntaxes are isomorphic and James Clark 's conversion tool— Trang —can convert between them without loss of information. RELAX NG has a simpler definition and validation framework than XML Schema, making it easier to use and implement. It also has the ability to use datatype framework plug-ins ; a RELAX NG schema author, for example, can require values in an XML document to conform to definitions in XML Schema Datatypes. Schematron

960-496: A more robust foundation to build responsive web apps. Xojo has ranked among the top 100 most popular programming languages as published by TIOBE, a company which rates the quality of software. The Xojo IDE is free to use for learning and development. Compiling or deploying applications with Xojo requires a license. Multiple license levels are available for purchase, enabling Desktop, Web, iOS and Android. Building applications for Linux Desktop and Console, including for Raspberry Pi,

1040-471: A new platform, Raspberry Pi. Xojo added many new features in 2018 and 2019, including support for macOS and iOS light/dark modes, a GraphicsPath for drawing Bézier curves, and a new DateTime class. In 2020, Xojo introduced a new web framework, which is a ground-up re-write that adds modern-looking new controls, support for Bootstrap themes, two layout modes and more. The new web framework takes advantage of all that modern web browsers have to offer, providing

1120-411: A product or service free of charge (typically digital offerings such as software, content, games, web services or other) while charging a premium for advanced features, functionality, or related products and services. For example, a fully functional feature-limited version may be given away for free, with advanced features disabled until a license fee is paid. The word freemium combines the two aspects of

1200-506: A rich datatyping system and allow for more detailed constraints on an XML document's logical structure. XSDs also use an XML-based format, which makes it possible to use ordinary XML tools to help process them. xs:schema element that defines a schema: RELAX NG (Regular Language for XML Next Generation) was initially specified by OASIS and is now a standard (Part 2: Regular-grammar-based validation of ISO/IEC 19757 – DSDL ). RELAX NG schemas may be written in either an XML based syntax or

1280-435: A server was hard to come by, so networks like Info-Mac were developed, consisting of non-profit mirror sites hosting large shareware libraries accessible via the web or ftp. With the advent of the commercial web hosting industry, the authors of shareware programs started their own sites where the public could learn about their programs and download the latest versions, and even pay for the software online. This erased one of

1360-432: A shareware game and a game demo is that the shareware game is (at least in theory) a complete working software program albeit with reduced content compared to the full game, while a game demo omits significant functionality as well as content. Shareware games commonly offered both single player and multiplayer modes plus a significant fraction of the full game content such as the first of three episodes, while some even offered

1440-567: A single user). The default database used with Xojo is SQLite . Unlike most programming environments, project source code is not stored in plain text files by default, but in a proprietary, single-file format. However, source code can be saved to a plain-text format for use with version control systems and can be exported to XML format as well. On March 11, 2014, Xojo launched Xojo Cloud, their cloud hosting service for Xojo web applications. The Xojo programming language looks similar to Visual Basic . The following code snippet placed in

1520-484: A small charge on floppy disk. These companies later made their entire catalog available on CD-ROM. One such distributor, Public Software Library (PSL), began an order-taking service for programmers who otherwise had no means of accepting credit card orders. Meanwhile major online service provider CompuServe enabled people to pay (register) for software using their CompuServe accounts. When AOL bought out CompuServe, that part of CompuServe called SWREG (Shareware Registration)

1600-421: A validity error must be able to report it, but may continue normal processing. A DTD is an example of a schema or grammar . Since the initial publication of XML 1.0, there has been substantial work in the area of schema languages for XML. Such schema languages typically constrain the set of elements that may be used in a document, which attributes may be applied to them, the order in which they may appear, and

1680-527: A vocabulary to refer to the constructs within an XML document, but does not provide any guidance on how to access this information. A variety of APIs for accessing XML have been developed and used, and some have been standardized. Existing APIs for XML processing tend to fall into these categories: Stream-oriented facilities require less memory and, for certain tasks based on a linear traversal of an XML document, are faster and simpler than other alternatives. Tree-traversal and data-binding APIs typically require

1760-461: Is a lexical , event-driven API in which a document is read serially and its contents are reported as callbacks to various methods on a handler object of the user's design. SAX is fast and efficient to implement, but difficult to use for extracting information at random from the XML, since it tends to burden the application author with keeping track of what part of the document is being processed. It

1840-456: Is a markup language and file format for storing, transmitting, and reconstructing arbitrary data. It defines a set of rules for encoding documents in a format that is both human-readable and machine-readable . The World Wide Web Consortium 's XML 1.0 Specification of 1998 and several other related specifications —all of them free open standards —define XML. The design goals of XML emphasize simplicity, generality, and usability across

1920-420: Is a delay to start the program or "nag screen" reminding the user that they haven't donated to the project. This nag feature and/or delayed start is often removed in an update once the user has donated to (paid for) the software. Nagware (also known as begware, annoyware or a nagscreen) is a pejorative term for shareware that persistently reminds the user to purchase a license. It usually does this by popping up

2000-726: Is a language for making assertions about the presence or absence of patterns in an XML document. It typically uses XPath expressions. Schematron is now a standard (Part 3: Rule-based validation of ISO/IEC 19757 – DSDL ). DSDL (Document Schema Definition Languages) is a multi-part ISO/IEC standard (ISO/IEC 19757) that brings together a comprehensive set of small schema languages, each targeted at specific problems. DSDL includes RELAX NG full and compact syntax, Schematron assertion language, and languages for defining datatypes, character repertoire constraints, renaming and entity expansion, and namespace-based routing of document fragments to different validators. DSDL schema languages do not have

2080-493: Is a style of software distribution similar to shareware, distributed by the author on the condition that users send the author a postcard . A variation of cardware, emailware, uses the same approach but requires the user to send the author an email . Postcardware, like other novelty software distribution terms, is often not strictly enforced. Cardware is similar to beerware . The concept was first used by Aaron Giles , author of JPEGView . Another well-known piece of postcardware

2160-578: Is an XML industry data standard. XML is used extensively to underpin various publishing formats. One of the applications of XML is in the transfer of Operational meteorology (OPMET) information based on IWXXM standards. The material in this section is based on the XML Specification . This is not an exhaustive list of all the constructs that appear in XML; it provides an introduction to the key constructs most often encountered in day-to-day use. XML documents consist entirely of characters from

2240-498: Is better suited to situations in which certain types of information are always handled the same way, no matter where they occur in the document. Pull parsing treats the document as a series of items read in sequence using the iterator design pattern . This allows for writing of recursive descent parsers in which the structure of the code performing the parsing mirrors the structure of the XML being parsed, and intermediate parsed results can be used and accessed as local variables within

2320-577: Is currently available for Microsoft Windows , macOS , 32-bit x86 Linux , and can compile 32-bit and 64-bit applications for Windows (Windows XP and higher), macOS (running on Intel or Apple silicon Macs using the Cocoa frameworks), x86 Linux, iOS , Android , the web, and Raspberry Pi. Xojo is self-hosted : the Xojo IDE is built with the current release of Xojo. The 2015r3 release includes 64-bit support for Desktop, Web and Console targets as well as

2400-549: Is free. Licenses can be purchased a la carte , in any combination required and include 1 year of access to new releases. Xojo Pro, a bundle offered by Xojo, includes the ability to compile for Desktop, iOS, Android, Web and Console, along with technical support, access to consulting leads, and a license that will work on three machines. Xojo also has a Pro Plus license that includes everything in Xojo Pro, plus additional support benefits and can be installed on up to six devices (for

2480-442: Is not permitted because the null character is one of the control characters excluded from XML, even when using a numeric character reference. An alternative encoding mechanism such as Base64 is needed to represent such characters. Comments may appear anywhere in a document outside other markup. Comments cannot appear before the XML declaration. Comments begin with <!-- and end with --> . For compatibility with SGML ,

2560-443: Is the roguelike game Ancient Domains of Mystery , whose author collects postcards from around the world. Orbitron is distributed as postcardware. Exifer is a popular application among digital photographers that has been postcardware. Caledos Automatic Wallpaper Changer is a "still alive" project cardware. "Empathy" is a postcardware for password-protected executables. Dual Module Player and Linux were also postcardware for

2640-509: The Internet . It is a textual data format with strong support via Unicode for different human languages . Although the design of XML focuses on documents, the language is widely used for the representation of arbitrary data structures , such as those used in web services . Several schema systems exist to aid in the definition of XML-based languages, while programmers have developed many application programming interfaces (APIs) to aid

2720-458: The Unicode repertoire. Except for a small number of specifically excluded control characters , any character defined by Unicode may appear within the content of an XML document. XML includes facilities for identifying the encoding of the Unicode characters that make up the document, and for expressing characters that, for one reason or another, cannot be used directly. Unicode code points in

2800-410: The infoset augmentation facility and attribute defaults. RELAX NG and Schematron intentionally do not provide these. A cluster of specifications closely related to XML have been developed, starting soon after the initial publication of XML 1.0. It is frequently the case that the term "XML" is used to refer to XML together with one or more of these other technologies that have come to be seen as part of

2880-449: The "Made with REALbasic Showcase" program to highlight applications created with the product. In 2009, a migration assistant was launched to help move code from Visual Basic. In 2010, to combat the perception that it was similar to the original BASIC, it was renamed Real Studio. The company announced Real Studio Web Edition, allowing developers to compile web applications without the knowledge of multiple web technologies. On June 4, 2013

2960-510: The Internet era, books compiling reviews of available shareware were published, sometimes targeting specific niches such as small business . These books would typically come with one or more floppy disks or CD-ROMs containing software from the book. As Internet use grew, users turned to downloading shareware programs from FTP or web sites. This spelled the end of bulletin board systems and shareware disk distributors. At first, disk space on

3040-464: The Open event of a Window displays a message box saying " Hello, World! " as the window loads: This code populates a ListBox with the values from an array: Shareware Shareware is a type of proprietary software that is initially shared by the owner for trial use at little or no cost. Often the software has limited functionality or incomplete documentation until the user sends payment to

3120-429: The XML core. Some other specifications conceived as part of the "XML Core" have failed to find wide adoption, including XInclude , XLink , and XPointer . The design goals of XML include, "It shall be easy to write programs which process XML documents." Despite this, the XML specification contains almost no information about how programmers might go about doing such processing. The XML Infoset specification provides

3200-555: The XML processor inserts in the DTD itself and in the XML document wherever they are referenced, like character escapes. DTD technology is still used in many applications because of its ubiquity. A newer schema language, described by the W3C as the successor of DTDs, is XML Schema , often referred to by the initialism for XML Schema instances, XSD (XML Schema Definition). XSDs are far more powerful than DTDs in describing XML languages. They use

3280-434: The allowable parent/child relationships. The oldest schema language for XML is the document type definition (DTD), inherited from SGML. DTDs have the following benefits: DTDs have the following limitations: Two peculiar features that distinguish DTDs from other schema types are the syntactic support for embedding a DTD within XML documents and for defining entities , which are arbitrary fragments of text or markup that

3360-489: The application is all that is required to disable the registration notices. In the early 1990s, shareware distribution was a popular method of publishing games for smaller developers, including then-fledgling companies Apogee Software (also known as 3D Realms ), Epic MegaGames (now Epic Games ), Ambrosia Software and id Software . It gave consumers the chance to play the game before investing money in it, and it gave them exposure that some products would be unable to get in

3440-621: The base language for communication protocols such as SOAP and XMPP . It is one of the message exchange formats used in the Asynchronous JavaScript and XML (AJAX) programming technique. Many industry data standards, such as Health Level 7 , OpenTravel Alliance , FpML , MISMO , and National Information Exchange Model are based on XML and the rich features of the XML schema specification. In publishing, Darwin Information Typing Architecture

3520-401: The behavior of programs that process HTML , which are designed to produce a reasonable result even in the presence of severe markup errors. XML's policy in this area has been criticized as a violation of Postel's law ("Be conservative in what you send; be liberal in what you accept"). The XML specification defines a valid XML document as a well-formed XML document which also conforms to

3600-419: The business model: "free" and "premium". It has become a popular model especially in the antivirus industry. Adware, short for "advertising-supported software", is any software package which automatically renders advertisements in order to generate revenue for its author. Shareware is often packaged with adware to lower the shareware fees or eliminate the need to charge users a fee. The advertisements may take

3680-423: The case of C1 characters, this restriction is a backwards incompatibility; it was introduced to allow common encoding errors to be detected. The code point U+0000 (Null) is the only character that is not permitted in any XML 1.1 document. The Unicode character set can be encoded into bytes for storage or transmission in a variety of different ways, called "encodings". Unicode itself defines encodings that cover

3760-544: The chief distinctions of shareware, as it was now most often downloaded from a central "official" location instead of being shared samizdat -style by its users. To ensure users would get the latest bug-fixes as well as an install untainted by viruses or other malware , some authors discouraged users from giving the software to their friends, encouraging them to send a link instead. Major download sites such as VersionTracker and CNet 's Download.com began to rank titles based on quality, feedback, and downloads. Popular software

3840-509: The company officially changed their name to Xojo, Inc. and Real Studio was renamed Xojo. Also on this date they released Xojo 2013 Release 1 which included an all-new user interface, full support for Cocoa on OS X , improved support for web applications, all new documentation and a new Introduction to Programming Using Xojo textbook that was designed for beginners to learn the fundamentals of object oriented programming. Xojo, Inc. calls it "the spiritual successor to Visual BASIC". The Xojo IDE

3920-429: The data structure and contain metadata . What is within the tags is data, encoded in the way the XML standard specifies. An additional XML schema (XSD) defines the necessary metadata for interpreting and validating XML. (This is also referred to as the canonical schema.) An XML document that adheres to basic XML rules is "well-formed"; one that adheres to its schema is "valid." IETF RFC 7303 (which supersedes

4000-402: The developer and the pirates where the developer disables pirated codes and the pirates attempt to find or generate new ones. Some software publishers have started accepting known pirated codes, using the opportunity to educate users on the economics of the shareware model. Some shareware relies entirely on the user's honesty and requires no password. Simply checking an "I have paid" checkbox in

4080-442: The direct use of almost any Unicode character in element names, attributes, comments, character data, and processing instructions (other than the ones that have special symbolic meaning in XML itself, such as the less-than sign, "<"). The following is a well-formed XML document including Chinese , Armenian and Cyrillic characters: The XML specification defines an XML document as a well-formed text, meaning that it satisfies

4160-432: The entire product as shareware while unlocking additional content for registered users. By contrast a game demo may offer as little as one single-player level or consist solely of a multiplayer map, this makes them easier to prepare than a shareware game. There are several widely accepted standards and technologies that are used in the development and promotion of shareware. XML Extensible Markup Language ( XML )

4240-523: The entire repertoire; well-known ones include UTF-8 (which the XML standard recommends using, without a BOM ) and UTF-16 . There are many other text encodings that predate Unicode, such as ASCII and various ISO/IEC 8859 ; their character repertoires are in every case subsets of the Unicode character set. XML allows the use of any of the Unicode-defined encodings and any other encodings whose characters also appear in Unicode. XML also provides

4320-498: The following ranges are valid in XML 1.0 documents: XML 1.1 extends the set of allowed characters to include all the above, plus the remaining characters in the range U+0001–U+001F. At the same time, however, it restricts the use of C0 and C1 control characters other than U+0009 (Horizontal Tab), U+000A (Line Feed), U+000D (Carriage Return), and U+0085 (Next Line) by requiring them to be written in escaped form (for example U+0001 must be written as &#x01; or its equivalent). In

4400-414: The form of a banner on an application window. The functions may be designed to analyze which websites the user visits and to present advertising pertinent to the types of goods or services featured there. The term is sometimes used to refer to software that displays unwanted advertisements, which typically are more intrusive and may appear as pop-ups , as is the case in most ad-oriented spyware . During

4480-418: The fully featured program until the trial period is up, and then most trialware reverts to either a reduced-functionality (freemium, nagware, or crippleware) or non-functional mode, unless the user purchases a full version. Trialware has become normalized for online Software as a Service (SaaS). WinRAR is a notable example of an unlimited trialware, i.e. a program that retains its full functionality even after

4560-658: The functions performing the parsing, or passed down (as function parameters) into lower-level functions, or returned (as function return values) to higher-level functions. Examples of pull parsers include Data::Edit::Xml in Perl , StAX in the Java programming language, XMLPullParser in Smalltalk , XMLReader in PHP , ElementTree.iterparse in Python , SmartXML in Red , System.Xml.XmlReader in

4640-438: The idea for shareware came to him "to some extent as a result of my psychedelic experience ". In 1983 Jerry Pournelle wrote of "an increasingly popular variant" of free software "that has no name, but works thus: 'If you like this, send me (the author) some money. I prefer cash. ' " In 1984, Softalk-PC magazine had a column, The Public Library , about such software. Public domain is a misnomer for shareware, and Freeware

4720-421: The installation of the intended software, the user is presented with a requirement to agree to the terms of click through an end-user license agreement or similar licensing which governs the installation of the software. Crippleware has vital features of the program, such as printing or the ability to save files, disabled or unwanted features like watermarks on screencasting and video editing software until

4800-648: The name to be generic, so its use became established over freeware and user-supported software . Fluegelman, Knopf, and Wallace clearly established shareware as a viable software distribution model by becoming wealthy. Prior to the popularity of the World Wide Web and widespread Internet access, shareware was often the only economical way for independent software authors to get their product onto users' desktops. Those with Internet or BBS access could download software and distribute it amongst their friends or user groups, who would then be encouraged to send

4880-550: The older RFC 3023 ), provides rules for the construction of media types for use in XML message. It defines three media types: application/xml ( text/xml is an alias), application/xml-external-parsed-entity ( text/xml-external-parsed-entity is an alias) and application/xml-dtd . They are used for transmitting raw XML files without exposing their internal semantics . RFC 7303 further recommends that XML-based languages be given media types ending in +xml , for example, image/svg+xml for SVG . Further guidelines for

SECTION 60

4960-404: The printed output, typically stating that the output was produced by an unlicensed copy. Some titles display a dialog box with payment information and a message that paying will remove the notice, which is usually displayed either upon startup or after an interval while the application is running. These notices are designed to annoy the user into paying. Postcardware, also called just cardware,

5040-449: The processing of XML data. The main purpose of XML is serialization , i.e. storing, transmitting, and reconstructing arbitrary data. For two disparate systems to exchange information, they need to agree upon a file format. XML standardizes this process. It is therefore analogous to a lingua franca for representing information. As a markup language , XML labels, categorizes, and structurally organizes information. XML tags represent

5120-622: The registration fee to the author, usually via postal mail. During the late 1980s and early 1990s, shareware software was widely distributed over online services , bulletin board systems and on diskettes. Contrary to commercial developers who spent millions of dollars urging users " Don't Copy That Floppy ", shareware developers encouraged users to upload the software and share it on disks. Commercial shareware distributors such as Educorp and Public Domain Inc printed catalogs describing thousands of public domain and shareware programs that were available for

5200-475: The retail space. With the Kroz series, Apogee introduced the "episodic" shareware model that became the most popular incentive for buying a game. While the shareware game would be a truly complete game, there would be additional "episodes" of the game that were not shareware and could only be legally obtained by paying for the shareware episode. In some cases these episodes were neatly integrated and would feel like

5280-487: The rules of a Document Type Definition (DTD). In addition to being well formed, an XML document may be valid . This means that it contains a reference to a Document Type Definition (DTD), and that its elements and attributes are declared in that DTD and follow the grammatical rules for them that the DTD specifies. XML processors are classified as validating or non-validating depending on whether or not they check XML documents for validity. A processor that discovers

5360-585: The software developer. Shareware is often offered as a download from a website . Shareware differs from freeware , which is fully-featured software distributed at no cost to the user but without source code being made available; and free and open-source software , in which the source code is freely available for anyone to inspect and alter. There are many types of shareware and, while they may not require an initial up-front payment, many are intended to generate revenue in one way or another. Some limit use to personal non- commercial purposes only, with purchase of

5440-469: The string "--" (double-hyphen) is not allowed inside comments; this means comments cannot be nested. The ampersand has no special significance within comments, so entity and character references are not recognized as such, and there is no way to represent characters outside the character set of the document encoding. An example of a valid comment: <!--no need to escape <code> & such in comments--> XML 1.0 (Fifth Edition) and XML 1.1 support

5520-429: The term freeware ; he described it "as an experiment in economics more than altruism". About the same time, Jim "Button" Knopf released PC-File , a database program, calling it user-supported software . Not much later, Bob Wallace produced PC-Write , a word processor, and called it shareware . Appearing in an episode of Horizon titled Psychedelic Science originally broadcast 5 April 1998, Bob Wallace said

5600-464: The trial period has ended. The rationale behind trialware is to give potential users the opportunity to try out the program to judge its usefulness before purchasing a license. According to industry research firm Softletter, 66% of online companies surveyed had free-trial-to-paying-customer conversion rates of 25% or less. SaaS providers employ a wide range of strategies to nurture leads, and convert them into paying customers. Freemium works by offering

5680-474: The use of XML in a networked context appear in RFC 3470 , also known as IETF BCP 70, a document covering many aspects of designing and deploying an XML-based language. XML has come into common use for the interchange of data over the Internet. Hundreds of document formats using XML syntax have been developed, including RSS , Atom , Office Open XML , OpenDocument , SVG , COLLADA , and XHTML . XML also provides

5760-472: The use of much more memory, but are often found more convenient for use by programmers; some include declarative retrieval of document components via the use of XPath expressions. XSLT is designed for declarative description of XML document transformations, and has been widely implemented both in server-side packages and Web browsers. XQuery overlaps XSLT in its functionality, but is designed more for searching of large XML databases . Simple API for XML (SAX)

5840-436: The user and requests an optional donation be paid to the programmer or a third-party beneficiary (usually a non-profit ). The amount of the donation may also be stipulated by the author, or it may be left to the discretion of the user, based on individual perceptions of the software's value. Since donationware comes fully operational (i.e. not crippleware ) with payment optional, it is a type of freeware . In some cases, there
