/*
* Note: This file contains most defines you'll wish to change if you
* wish to adopt ChkTeX to a new system. It is, as you might notice,
* heavily documented. If you wish to get into the internals of ChkTeX,
* the interesting stuff is at the bottom of this file, and in the .c
* files. However, you should also take a look at the "config.h.in" file
* in this directory if you haven't got a shell able to run the "configure"
* script.
*
* This program relies heavily on that the system which
* automagically free()'s all malloc()'ed memory, works. The program
* itself does not call free() very much. This is because we're doing
* lots of tiny allocations, and a properly designed pooling system will
* hopefully do a quicker job than we'll be able to do. So there.
*
* To keep things simple, we trust that the fclose()'ing of fopen()'ed
* also happens automagically.
*
* Please use the getopt included, as we will modify optarg during
* command processing.
*
* You may wish to modify the SetupVars() (OpSys.c) to better suit your
* preferences. In any case, it should put the filename (and full path)
* of the `.chktexrc' file into the ConfigFile array. The array is sized
* BUFSIZ bytes.
*
* The program does also assume that __unix__ is defined if the source is
* compiled on a UNIX machine.
