Usage: msgcmp [OPTION] def.po ref.pot Compare two Uniforum style .po files to check that both contain the same set of msgid strings. The def.po file is an existing PO file with the translations. The ref.pot file is the last created PO file, or a PO Template file (generally created by 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. Mandatory arguments to long options are mandatory for short options too. Input file location: def.po translations ref.pot references to the sources -D, --directory=DIRECTORY add DIRECTORY to list for input files search Operation modifiers: -m, --multi-domain apply ref.pot to each of the domains in def.po -N, --no-fuzzy-matching do not use fuzzy matching --use-fuzzy consider fuzzy entries --use-untranslated consider untranslated entries Input file syntax: -P, --properties-input input files are in Java .properties syntax --stringtable-input input files are in NeXTstep/GNUstep .strings syntax Informative output: -h, --help display this help and exit -V, --version output version information and exit Report bugs to <email@example.com>.
