<p>'lim_test' scans the given source file and lists the tokens on stdout.
The source file must be conform with the language parameter. It uses the image file
of the scanner table [Language.lim].
<p>The current version doesn't support the embedded language facility.

<p>The options 'prepar' and 'premac' are only useful with styx-like preprocessing.
<p>If your language uses the same preprocessing directives as specified in [styx.sty],
but differnt macro token identifiers and keywords, the option 'prepar' can be used to
enable preprocessing and specify the differences as a comma separated list:
</p>
<ol>
<li><b>0~name of identifier token</b>
<li><b>1~name of macro definition token</b>
<li><b>2~name of argument separator token</b>
<li><b>3~name of include token</b>
<li><b>4~name of conditional token</b>
<li><b>5~name of undefine token</b>
<li><b>6~#macro keyword</b>
<li><b>7~#end keyword</b>
<li><b>8~#ifdef keyword</b>
<li><b>9~#ifndef keyword</b>
<li><b>10~#else keyword</b>
<li><b>11~#include keyword</b>
<li><b>12~#undefine keyword</b>
<li><b>13~environment variable or path list as search path for include files</b>
<li><b>14~include file character set ( default: charset-option )</b>
</ol>
<p>The option 'premac' supports pre-defined macros in connection with
styx-like preprocessing.
<p>Dynamic library support is a prerequisite for the user-defined callback handler.
<BR>
<BR>
<H2>Environment</H2>
An environment variable will be specified as followed: <B>-<Name>=<Value></B>
<BR>The default value will be applied when no environment variable was specified.
