The xopo utility simplifies libxo format strings into the form used for gettext lookups by the libxo library. Using xopo, users can turn .pot files generated by xgettext into data useful for libxo-enabled applications.
Since gettext uses the string as the key into the message catalog, libxo uses a simplified version of the format string that removes unimportant field formatting and modifiers, stopping minor formatting changes from impacting the expensive translation process. A developer change such as changing "/%06d" to "/%08d" should not force hand inspection of all .po files.
xopo inspects the input file, looking for lines that begin with "msgid" which carry format strings as the remainder of the input line. These strings are passed to libxo for simplification and the resulting strings are replaced into the output stream, allowing xopo to operated as a filter.
