[tex-live] kpsewhich

[Nelson H. F. Beebe]

I agree with Hans Hagen's sentiments: -expand-var should be followed
by a variable name, not the backslash and quote-protected expansion
thereof that is awkward to type, and nonportable between Unix and
Windows.  The program can easily invoke getenv() to get the value of
the named variable.  I too would therefore like to see

	kpsewhich -expand-var SELFAUTOPARENT

For the book that I'm co-authoring, we developed a script that works
like this:

	% pathfind PATH gcc
	/usr/local/bin/gcc

	% pathfind --all PATH gcc
	/usr/local/bin/gcc
	/usr/bin/gcc
	/usr/local/gnat/bin/gcc

	% pathfind TEXFONTS cmr10.tfm cmman.pfb
	/usr/local/lib/tex/fonts/cm/tfms/cmr10.tfm
	/usr/local/lib/tex/fonts/ps/cmman.pfb

Using the name of the variable, rather than its value, is much
cleaner.
