[tex-k] Re: Web2C TeX

[Karl Berry]

    Can you tell me how Web2C TeX searches for input files? I'm trying
    to find an environment variable for the input path, but I can't find
    one. Thanks.

The basic environment variable is TEXINPUTS, as it has been since day 1
of Unix TeX :).  (Howard Trickey et al.)

The path searching scheme in general is unfortunately complex.  See the
kpathsea and web2c Texinfo manuals for details.  They're in the source
and I'm sure they're all over the web as well.

Hope this helps,
