[Po4a-Devel] Asciidoc: How to format entry for "//po4a: entry"?

Hello, I'm trying to include an attribute string in the .pot file, but haven't found the correct formatting yet. This is what I have in the file header: //po4a: entry :man manual: = ionice(1) :doctype: manpage :man manual: User commands :man source: util-linux {release-version} :page-layout: base :command: ionice I like to translate the value of the "man manual" attribute, but it isn't recognized. This is the command I use: po4a-gettextize -f asciidoc -m ionice.1.adoc -p ionice.1.pot Tried some other versions, with or without colons, with or without citation, even the attribute entry instead of the attribute name. What I have to do to get this into the .pot file? Best Regards, Mario
