web2c: Path searching

 
 3.3 Path searching
 ==================
 
 All of the Web2c programs, including TeX, which do path searching use
 the Kpathsea routines to do so.  The precise names of the environment
 and configuration file variables which get searched for particular file
DONTPRINTYET  formatted are therefore documented in the Kpathsea manual (⇒
 (kpathsea)Supported file formats).  Reading 'texmf.cnf' (*noteDONTPRINTYET DONTPRINTYET  formatted are therefore documented in the Kpathsea manual (⇒
 (kpathsea)Supported file formats).  Reading 'texmf.cnf' (⇒
 (kpathsea)Config files), invoking 'mktex...' scripts (*noteDONTPRINTYET DONTPRINTYET  formatted are therefore documented in the Kpathsea manual (⇒
 (kpathsea)Supported file formats).  Reading 'texmf.cnf' (⇒
 (kpathsea)Config files), invoking 'mktex...' scripts (⇒
 (kpathsea)mktex scripts), and so on are all handled by Kpathsea.
 
    The programs which read fonts make use of another Kpathsea feature:
 'texfonts.map', which allows arbitrary aliases for the actual names of
 font files; for example, 'Times-Roman' for 'ptmr8r.tfm'.  The
 distributed (and installed by default) 'texfonts.map' includes aliases
 for many widely available PostScript fonts by their PostScript names.
