Purpose: to contain discussion relating to an installation directory structure that is recommended for people writing tcl extensions or applications.


[LV] Jump right in and add info as you see needed:

By default, extensions should use two main groups of locations for installing things, one for architecture-independent files, and one for architecture-dependent files.

'''--prefix''' specifies the location of the architecture-independent files (e.g. Tcl scripts, header files, documentation) and is conventionally ''/usr/local'' by default.  Beneath this location, the following places are usually defined:

   '''include''':   Place to put header file(s) needed when writing code against a library.
   '''lib''':   Location where Tcl-only extensions are installed.
   '''lib'''/''extension.version.level'':   Location for ''pkgIndex.tcl'' files, tcl files, etc.
   '''bin''':   Place to install Tcl-only applications.
   '''man''':   Place to install nroff manual pages.

'''--exec-prefix''' specifies the location of architecture-dependent files (binary extensions, etc.)

   '''lib''':   Location where binary extensions and their ''pkgIndex.tcl'' are installed.
   '''lib'''/''extension.version.level'':   Location for ''pkgIndex.tcl'' files, .so/.dll files, static archives (.a, .lib), etc.
   '''bin''':   Location where binary applications are installed.
