@example msgcmp [@var{option}] @var{def}.po @var{ref}.pot @end example The @code{msgcmp} program compares two Uniforum style .po files to check that both contain the same set of msgid strings. The @var{def}.po file is an existing PO file with the translations. The @var{ref}.pot file is the last created PO file, or a PO Template file (generally created by @code{xgettext}). This is useful for checking that you have translated each and every message in your program. Where an exact match cannot be found, fuzzy matching is used to produce better diagnostics. @subsection Input file location @table @samp @item @var{def}.po Translations. @item @var{ref}.pot References to the sources. @item -D @var{directory} @itemx --directory=@var{directory} Add @var{directory} to the list of directories. Source files are searched relative to this list of directories. @end table @subsection Operation modifiers @table @samp @item -m @itemx --multi-domain Apply @var{ref}.pot to each of the domains in @var{def}.po. @end table @subsection Informative output @table @samp @item -h @itemx --help Display this help and exit. @item -V @itemx --version Output version information and exit. @end table
