+/* 
+ *
+ *  MINI_EPN.C - Mini Embedded Perl Nagios
+ *  Contributed by Stanley Hopcroft
+ *  Modified by Douglas Warner
+ *  Last Modified: 05/02/2002
+ *
+ *  $Id$
+ *
+ *  This is a sample mini embedded Perl interpreter (hacked out checks.c and 
+ *  perlembed) for use in testing Perl plugins. 
+ *
+ *  It can be compiled with the following command (see 'man perlembed' for 
+ *  more info):
+ *
+ *  gcc -omini_epn mini_epn.c `perl -MExtUtils::Embed -e ccopts -e ldopts`
+ *
+ *  NOTES:  The compiled binary needs to be in the same directory as the p1.pl
+ *  file supplied with Nagios (or vice versa)
+ *  When using mini_epn to test perl scripts, you must place positional
+ *  arguments immediately after the file/script and before any arguments
+ *  processed by Getopt
+ *
