6 TeX support
*************

Although the basic features in Kpathsea can be used for any type of path
searching, it came about, as usual, with a specific application in mind:
I wrote Kpathsea specifically for TeX system programs.  I had been
struggling with the programs I was using (Dvips, Xdvi, and TeX itself)
having slightly different notions of how to specify paths; and debugging
was painful, since no code was shared.

   Therefore, Kpathsea provides some TeX-specific formats and features.
Indeed, many of the purportedly generic path searching features were
provided because they seemed useful in that conTeXt (font lookup,
particularly).

   Kpathsea provides a standard way to search for files of any of the
supported file types; glyph fonts are a bit different than all the rest.
Searches are based solely on names of files, not their contents--if a GF
file is (mis)named 'cmr10.600pk', it will be found as a PK file.

Supported file formats

File types Kpathsea knows about.

File lookup

Searching for most kinds of files.

Glyph lookup

Searching for bitmap fonts.

Suppressing warnings

Avoiding warnings via TEX_HUSH.

mktex scripts

Generating files at runtime.
