=head1 NAME
fm_check_config - Runs some tests on the given config file.
=head1 VERSION
version 0.7.2
=head1 SYNOPSIS
fm_check_config [options] [PATH_TO_CONFIG.CDB] PATH_TO_CONFIG.PRO
This script compares a given config.pro file with the loaded options within
print "the given cdb file. The config.pro file is also checked against duplicate
print "entries of options.
Options:
  --help             -?   Prints this help.
  --version               Prints current version.
  --verbose          -v   The verbose level. 0 - least output, 2 most output (Default: 1).
  --case-insensitive -i   Ignores all differences, with existing value, but different cases (e.g. YES and yes)
                          The default is to print those differences in cyan. The count of ignored
                          values is displayed.
  --description      -d   Displays the description of each printed option.
                          Only available, if a database can be queried.
Normally you won't specify a cdb file. Just run fm_create_help before you run this script
to create a database. If you do not want or cannot create a database for the installtion
you want to use, specify a cdb file.
If no cdb file is given, it tries to figure out the correct installation with help of $ENV{PATH}.
Example:
  fm_check_config c:\proeWildfire5\text\config.cdb c:\proeWildfire5\text\config.pro
=head1 DESCRIPTION
C<fm_check_config> checks the given config file against the given cdb file.
Therefore it can check whether all given options and there specified values
are supported. It also checks whether options are duplicated within the config
file.
