/*
* In order to find tk.tcl during initialization, the following script
* is invoked by Tk_Init(). It looks in several different directories:
*
* $tk_library - can specify a primary location, if set
* no other locations will be checked
*
* $env(TK_LIBRARY) - highest priority so user can always override
* the search path unless the application has
* specified an exact directory above
*
* $tcl_library/../tk$tk_version
* - look relative to init.tcl in an installed
* lib directory (e.g. /usr/local)
*
* <executable directory>/../lib/tk$tk_version
* - look for a lib/tk<ver> in a sibling of
* the bin directory (e.g. /usr/local)
*
* <executable directory>/../library
* - look in Tk build directory
*
* <executable directory>/../../tk$tk_patchLevel/library
* - look for Tk build directory relative
* to a parallel build directory
*
* The first directory on this path that contains a valid tk.tcl script
* will be set ast the value of tk_library.
*
* Note that this entire search mechanism can be bypassed by defining an
* alternate tkInit procedure before calling Tk_Init().
