Updated gencat(1) page from T. Lambert:

"Here is a new gencat(1) man page.  It contains examples
  and information not in the current man page (e.g., file
  format) per the X/Open documentation.  It also updates some
  aspects of the X/Open documentation (e.g., the X/Open
  document neglects to say how to embed a $quote character
  into a string)."

 .Nm gencat
 .Nd NLS catalog compiler
 .Sh SYNOPSIS
-.Nm gencat
+.Nm 
 .Ar "output-file"
-.Ar "input-file..."
+.Ar "input-files..."
 .Sh DESCRIPTION
 The
-.Nm gencat
-utility compiles a text NLS input file into a catalog in a binary
-format used by the
-.Xr catclose 3 ,
-.Xr catgets 3
-and
-.Xr catopen 3
-functions.
+.Nm
+utility merges the text NLS input files
+.Ar "input-files..."
+into a formatted message catalog file
+.Ar "output-file" .
+The file
+.Ar "output-file"
+will be created if it does not already exist.  If
+.Ar "output-file"
+does exist, its messages will be included in the new
+.Ar "output-file" .
+If set and message numbers collide, the new message text defined in
+.Ar "input-files..."
+will replace the old message text currently contained in
+.Ar "output-file" .
+.Sh INPUT FILES
+The format of a message text source file is defined below.  Note that
+the fields of a message text source line are separated by a single space
+character: any other space characters are considered to be part of the
+field contents.
+.Pp
+.Bl -tag -width
+.It Li $set Ar n comment
+This line specifies the set identifier of the following messages until
+the next
+.Li $set
+or end-of-file appears.  The argument
+.Ar n
+is the set identifier which is defined as a number in the range
+[1, (NL_SETMAX)].  Set identifiers must occur in ascending order within
+a single source file, but need not be contiguous.  Any string following
+a space following the set identifier is treated as a comment.  If no
+.Li $set
+directive  is specified in a given source file, all messages will
+be located in the default message set NL_SETD.
+.It Li $del Ar n comment
+This line deletes messages from set
+.Ar n
+from a message catalog.  The
+.Ar n
+specifies a set number.  Any string following a space following the set
+number is treated as a comment.
+.It Li $ Ar comment
+A line beginning with
+.Li $
+followed by a space is treated as a comment.
+.It Ar m message-text
+A message line consists of a message identifier
+.Ar m
+in the range [1, (NL_MSGMAX)].  The
+.Ar message-text
+is stored in the message catalog with the set identifier specified by
+the last
+.Li $set
+directive, and the message identifier
+.Ar m .
+If the
+.Ar message-text
+is empty, and there is a space character following the message identifier,
+an empty string is stored in the message catalog.  If the
+.Ar message-text
+is empty, and if there is no space character following the message
+identifier, then the existing message in the current set with the
+specified message identifier is deleted from the catalog.  Message
+identifiers must be in ascending order within a single set, but
+need not be contiguous.  The
+.Ar message-text
+length must be in the range [0, (NL_TEXTMAX)].
+.It Li $quote Ar c
+This line specifies an optional quote character
+.Ar c
+which can be used to surround
+.Ar message-text
+so that trailing space or empty messages are visible in message
+source files.  By default, or if an empty
+.Li $quote
+directive is specified, no quoting of
+.Ar message-text
+will be recognized.
+.El
+.Pp
+Empty lines in message source files are ignored.  The effect of lines
+beginning with any character other than those described above is
+undefined.
+.Pp
+Text strings can contain the following special characters and escape
+sequences.  In addition, if a quote character is defined, it may be
+escaped as well to embed a literal quote character.

+A backslash character immediately before the end of the line in a file

+If the character following the backslash is not one of those specified,
+the backslash is ignored.
