To ''install'' a piece of software is the process of getting it into a system in a way that it will operate appropriately. Some software has simple installation requirements - [tclkit] for instance needs only be present in a directory that will be searched when you invoke it. Other software requires a bit more work - while some software requires quite a lot of work to get installed. Many times, software comes with instructions regarding installation. If a particular piece of software does not come with such instructions, then one can either contact the author or other maintainers asking for assistance, or one can contact a web forum or usenet group which has a background familar with your computer operating system (or sometimes with the language being used in the application - or even sometimes a web forum specifically for the software package!) where one can ask for help. ---- [RS]: Self-contained scripts [[we need a wiki page for what this phrase means and techniques to accomplish it]] also need no installation, if they do [exec magic] for Unix, and a regular Tcl installation (with .tcl association, etc.) is present on Windows. In place of delivering separate icon files, they may be put in the script as [base64] encoded data, and loaded as such. ---- [category glossary]
