- * 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().
