kpathsea: mktex scripts

 
 6.5 'mktex' scripts
 ===================
 
 If Kpathsea cannot otherwise find a file, for some file types it is
 configured by default to invoke an external program to create it
 dynamically (⇒mktex configuration).  These are collectively known
 as "'mktex' scripts", since most of them are named 'mktex...'.
 
    For example, this is useful for fonts (bitmaps, TFM's, and
 arbitrarily-sizable Metafont sources such as the Sauter and EC fonts),
 since any given document can use fonts never before referenced.
 Building all fonts in advance is therefore impractical, if not
 impossible.
 
    It is also useful for the TeX '.fmt' (and Metafont '.base' and
 Metapost '.mem' files, ⇒(Web2c)Memory dumps), where
 pre-generating every format consumes a lot of both time and space.
 
    The script is passed the name of the file to create and possibly
 other arguments, as explained below.  It must echo the full pathname of
 the file it created (and nothing else) to standard output; it can write
 diagnostics to standard error.
