A message is selected if it comes from one of the specified source files, or if it comes from one of the specified domains, or if -J is given and its context (msgctxt) matches MSGCTXT-PATTERN, or if -K is given and its key (msgid or msgid_plural) matches MSGID-PATTERN, or if -T is given and its translation (msgstr) matches MSGSTR-PATTERN, or if -C is given and the translator’s comment matches COMMENT-PATTERN, or if -X is given and the extracted comment matches EXTRACTED-COMMENT-PATTERN.

When more than one selection criterion is specified, the set of selected messages is the union of the selected messages of each criterion.
