/*
* In order to find init.tcl during initialization, the following script
* is invoked by Tcl_Init(). It looks in several different directories:
*
* $tcl_library - can specify a primary location, if set
* no other locations will be checked
*
* $env(TCL_LIBRARY) - highest priority so user can always override
* the search path unless the application has
* specified an exact directory above
*
* $tclDefaultLibrary - this value is initialized by TclPlatformInit
* from a static C variable that was set at
* compile time
*
* $tcl_libPath - this value is initialized by a call to
* TclGetLibraryPath called from Tcl_Init.
*
* The first directory on this path that contains a valid init.tcl script
* will be set as the value of tcl_library.
*
* Note that this entire search mechanism can be bypassed by defining an
* alternate tclInit procedure before calling Tcl_Init().
