their initialization.  They call this procedure to look for their
script library in several standard directories.
The last component of the name of the library directory is
normally \fIbasenameversion\fR
(e.g., tk8.0), but it might be
.QW library
when in the build hierarchies.
The \fIpatch\fR argument is not used.
The \fIinitScript\fR file will be sourced into the interpreter
once it is found.  The directory in which this file is found is
stored into the global variable \fIvarName\fR.
If this variable is already defined (e.g., by C code during
application initialization) then no searching is done.
Otherwise the search looks in these directories:
the directory named by the environment variable \fIenVarName\fR;
