More sophisticated shell scripts for invoking SLaTeX
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The contents of this directory may be skipped by all
but the brave.

TEXINPUT(S) is a list of directories where TeX looks
for its \input files.  SLaTeX keeps track of
\input files in the list SLaTeX.*texinputs*, which is
ideally the same as TEXINPUT(S).  However, many TeX
implementations allow abbreviations in TEXINPUT(S),
whereby several subdirectories are concisely
represented by a single parent directory.  The SLaTeX
script file created by the configuration process is
too naive to expand out the TEXINPUT(S).  In any case,
it is rather moot if SLaTeX itself can perform file
search, since Scheme has no portable file search
capability.  Thus, it is possible that only files that
are in the current directory or are explicitly named
get treated by SLaTeX. Luckily, this is often
sufficient, since SLaTeX only needs to process user's
TeX files that contain Scheme code, and the files in
the path TEXINPUT(S) that are lost to consideration
are non-user files anyway.  If, however, your Scheme
does have file search, and you exploit the
abbreviation mechanism in TEXINPUT(S), you should
improve the script -- and the script language.

An example of such improved (arguably anal) scripts is
provided in the file scripts\slatex.cmd, intended for
use with emtex and scm.  You may use it (with your
personal modifications) if you wish to recognize fancy
TEXINPUT(S).  You may also use it as a model to write
your own scripts in other scripting languages, e.g.,
in Perl or Tcl or in Scheme itself (provided your
dialect is powerful enough to do file search).
