The -h + * option triggers the creation of these definitions and specifies + * the name to use. + * + * msg.c a data array of message strings. The msg.h definitions are + * offsets into this array.

The + * -m option triggers this output and specifies the filename to be + * used. + * + * The template file is processed based on the first character of each line: + * + * # or $ entries are copied (as is) to the message file (messages). + * + * @ token(s) entries are translated.

The reserved output indicator _END_ disables output to + * the message file. The use of these two indicators provides for + * only those message strings that require translation to be output + * to the message file. + * + * Besides the reserved output indicators, a single token is taken + * to be a message identifier which will be subsituted for a + * `setid' for catgets(3c) output, or a `domain' name for + * gettext(3i) output. This value is determine by substituting the + * token for the associated definition found in the message + * identifier file (specified with the -i option). + * + * Multiple tokens are taken to be a message definition followed by + * the associated message string.
