It needs some special markup in th e texinfo and tries best to get a create man page. It has been designed for the GnuPG man pages and thus only a few texinfo commands are supported. To use this you need to add the following macros into your texinfo source: @macro manpage {a} @end macro @macro mansect {a} @end macro @macro manpause @end macro @macro mancont @end macro They are used by yat2m to select parts of the Texinfo which should go into the man page. These macros need to be used without leading left space. Processing starts after a "manpage" macro has been seen. "mansect" identifies the section and yat2m make sure to emit the sections in the proper order. Note that @mansect skips the next input line if that line begins with @subsection or @chapheading. To insert verbatim troff markup, the follwing texinfo code may be used: @ifset manverb .B whateever you want @end ifset alternativly a special comment may be used: @c man:.B whatever you want This is useful in case you need just one line. If you want to include parts only in the man page but keep the texinfo translation you may use: @ifset isman stuff to be rendered only on man pages @end ifset or to exclude stuff from man pages: @ifclear isman stuff not to be rendered on man pages @end ifclear the keyword @section is ignored, however @subsection gets rendered as ".SS". @menu is completely skipped. Several man pages may be extracted from one file, either using the --store or the --select option. */ #include #include #include #include #include #include #include #include #include #define PGM "yat2m" #define VERSION "0.5" /* The maximum length of a line including the linefeed and one extra character. */ #define LINESIZE 1024 /* Option flags. */ static int verbose; static int quiet; static int debug; static const char *opt_source; static const char *opt_release; static const char *opt_select; static const char *opt_include; static int opt_store; /* Flag to keep track whether any error occurred. */ static int any_error; /* Object to store one line of content. */ struct line_buffer_s { struct line_buffer_s *next; int verbatim; /* True if LINE contains verbatim data.
