"[+NAME?msggen - generate a machine independent formatted message catalog]"
"[+DESCRIPTION?\bmsggen\b merges the message text source files \amsgfile\a"
" into a machine independent formatted message catalog \acatfile\a."
" The file \acatfile\a will be created if it does not already exist."
" If \acatfile\a does exist, its messages will be included in the new"
" \acatfile\a. If set and message numbers collide, the new message"
" text defined in \amsgfile\a will replace the old message text"
" currently contained in \acatfile\a. Non-ASCII characters must be"
" UTF-8 encoded. \biconv\b(1) can be used to convert to/from UTF-8.]"
"[f:format?List the \bprintf\b(3) format signature for each message in"
" \acatfile\a. A format signature is one line containing one character"
" per format specification:]{"
" [c?char]"
" [d?double]"
" [D?long double]"
" [f?float]"
" [h?short]"

" [l?long]"

" [t?ptrdiff_t]"

"}"
"[l:list?List \acatfile\a in UTF-8 \amsgfile\a form.]"
"[s:set?Convert the \acatfile\a operand to a message set number and"
" print the number on the standard output.]"
"[+EXTENDED DESCRIPTION?Message text source files are in \bgencat\b(1)"
" format, defined as follows. Note that the fields of a message text"
" source line are separated by a single blank character. Any other"
" blank characters are considered as being part of the subsequent"
" field. The \bNL_*\b constants are defined in one or both of"
" \b<limits.h>\b and \b<nl_types.h>\b.]{"
" [+$ \acomment\a?A line beginning with \b$\b followed by a"
" blank character is treated as a comment.]"
" [+$delset \an\a \acomment\a?This line deletes message set"
" \an\a from an existing message catalog. \an\a"
" denotes the set number [1, \bNL_SETMAX\b]]. Any"
" text following the set number is treated as a"
" comment.]"
" [+$quote \ac\a?This line specifies an optional quote"
" character \ac\a, which can be used to surround"
" \amessage-text\a so that trailing spaces or"
" empty messages are visible in a message source"
" line. By default, or if an empty \b$quote\b"
" directive is supplied, no quoting of \amessage-text\a"
" will be recognized.]"
" [+$set \an\a \acomment\a?This line specifies the set"
" identifier of the following messages until the next"
" \b$set\b or end-of-file appears. \an\a denotes the set"
" identifier, which is defined as a number in the range"
" [1, \bNL_SETMAX\b]]. Set numbers need not be"
" contiguous. Any text following the set identifier is"
" treated as a comment. If no \b$set\b directive is"
" specified in a message text source file, all messages"
" will be located in message set \b1\b.]"
" [+$translation \aidentification\a \aYYYY-MM-DD\a[,...]]?Append"
" translation info to the message catalog header. Only"
" the newest date for a given \aidentification\a"
" is retained in the catalog. Multiple translation lines"
" are combined into a single \b,\b separated list.]"
" [+\am\a \amessage-text\a?\am\a denotes the message identifier,"
" which is defined as a number in the range"
" [1, \bNL_MSGMAX\b]]. The message-text is stored in the"
" message catalogue with the set identifier specified by"
" the last \b$set\b directive, and with message"
" identifier \am\a. If the \amessage-text\a is empty,"
" and a blank character field separator is present, an"
" empty string is stored in the message catalogue. If a"
" message source line has a message number, but neither"
" a field separator nor \amessage-text\a, the existing"
" message with that number (if any) is deleted from the"
" catalogue. Message identifiers need not be contiguous."
