Supported file formats
======================

  Kpathsea has support for a number of file types.  Each file type has a
list of environment and config file variables that are checked to define
the search path, and most have a default suffix that plays a role in
finding files (see the next section).  Some also define additional
suffixes, and/or a program to be run to create missing files on the fly.

  Since environment variables containing periods, such as
`TEXINPUTS.latex', are not allowed on some systems, Kpathsea looks for
environment variables with an underscore, e.g., `TEXINPUTS_latex'
(Note: Config files).

  The following table lists the above information.

`afm'

     `TEXPSHEADERS', `PSHEADERS'; additional suffix `.pro'.

`tex'
     (TeX source, Note: tex invocation.)
     `TEXINPUTS'; suffix `.tex'; additional suffixes: none, because
     such a list cannot be complete; dynamic creation program:
     `mktextex'.

`TeX system documentation'
     (Documentation files for the TeX system) `TEXDOCS'.

`TeX system sources'
     (Source files for the TeX system) `TEXSOURCES'.

`texpool'
     (TeX program strings, Note: pooltype invocation.

)  `TRFONTS'.

`truetype fonts'
     (TrueType outline fonts) `TTFONTS'; suffixes `.ttf', `.ttc'.

`type1 fonts'
     (Type 1 PostScript outline fonts, Note: Glyph files.

     suffixes `.pfa', `.pfb'.

`type42 fonts'
     (Type 42 PostScript outline fonts) `T42FONTS'.

`vf'
     (virtual fonts, Note: Virtual fonts.)
     `VFFONTS', `TEXFONTS'; suffix `.vf'.

  There are two special cases, because the paths and environment
variables always depend on the name of the program: the variable name is
constructed by converting the program name to upper case, and then
appending `INPUTS'.  Assuming the program is called `foo', this gives
us the following table.

`other text files'
     (text files used by `foo') `FOOINPUTS'.

`other binary files'
     (binary files used by `foo') `FOOINPUTS'.

  If an environment variable by these names are set, the corresponding
`texmf.cnf' definition won't be looked at (unless, as usual, the
environment variable value has an extra `:').  Note: Default
expansion.

  For the font variables, the intent is that:
   * `TEXFONTS' is the default for everything.

   * `GLYPHFONTS' is the default for bitmap (or, more precisely,
     non-metric) files.

   * Each font format has a variable of its own.

   * Each program has its own font override path as well; e.g.,
     `DVIPSFONTS' for Dvipsk.  Again, this is for bitmaps, not metrics.
