It has no +AT&T code and is therefore freely distributable. + +Tim Theisen <tim@cs.wisc.edu> + +===================================================================== + +This is the modified code for the groff. It uses the different +devxxx format that is ascii rather than binary as in the +Berkeley distribution. Since groff does not have the \Ds option +for line drawing (dotted, dashed, etc.), this version includes +the routines for drawing curves and arcs, so it does not use the +\D~, \Da nor \Dc. Although also included in here is a routine +for drawing the optional gremlin style curves, it is not used +because the gremlin editor uses the conventional spline +algorithm. The Berkeley grn has the choice of different +stipples. Here, only different shades of gray will be painted +depending on the gremlin file. It is possible to upgrade this at +a later time. (Daniel Senderowicz <daniel@synchrods.com> 12/28/99) + +===================================================================== + +It has been further modified by Werner Lemberg <wl@gnu.org> to fit +better into the groff package. + + . Replaced Makefile with Makefile.sub. + + . Removed dev.h since it is unused. + + . Renamed grn.1 to grn.man; this man page has been extensively + revised. + + . Used error() and fatal() from libgroff for all source files. + + . Renamed *.c to *.cc; updates as needed for C++ (prototypes, proper + casts, standard header files etc). Heavy formatting. + + . main.cc: + + Using groff's default values instead of DEVDIR, DEFAULTDEV, PRINTER, + TYPESETTER, and GREMLIB. + + `res' is now an integer. + + Added `-C' command flag (for compatibility mode) as with other + preprocessors. + + Added `-F' and `-v' option (similar to troff). + + Renamed `-L' option to `-M' for consistence. + + Removed `-P' option. + + Using font::load_desc() for scanning DESC files. + + Removed SYSV-specific code. + + Using macro_path.open_file() for getting gremlin graphic files. + + Added usage(). |
