1: Gforth is a fast and portable implementation of the ANS Forth
2: language. It works nicely with the Emacs editor, offers some nice
3: features such as input completion and history, backtraces, a
4: decompiler and a powerful locals facility, and it has a comprehensive
5: manual. Gforth combines traditional implementation techniques with
6: newer techniques for portability and performance: its inner
7: interpreter is direct threaded with several optimizations, but you can
8: also use a traditional-style indirect threaded interpreter. Gforth is
9: distributed under the GNU General Public license (see COPYING).
10:
11: Gforth runs under GNU, BSD, and similar systems, MS Windows and MacOS X
12: and should not be hard to port to other systems supported by GCC. This
13: version has been tested successfully on the following platforms:

62: Read INSTALL for installation instructions from source, or INSTALL.DOS
63: for DOS, Windows, and OS/2 from source, or INSTALL.BINDIST if you have
64: a binary package distributed as .tar.gz or .zip file. If you received
65: a self-installing executable, just run it and follow the instructions.
66:
67: To start the system, just say `gforth' (after installing it).
68:
69: You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
70: and its mirrors or at
71:
72: http://www.complang.tuwien.ac.at/forth/gforth/
73: or
74: ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/
75:
76: The latter site also contains binary distributions of Gforth for some
77: popular platforms.
78:
79: If you want to work on Gforth, mail me. Tasks to be done can be found
80: in ToDo; but if you would like to do something not mentioned there,
81: it's ok, too. In any case, we would like to hear what you are
82: doing. The most important task IMO is the foreign language interface
83: for C.
84:
85: On popular request, here are the meanings of unusual file extensions:
86:
87: *.fs Forth stream source file (include with "include <file>" from within
88: gforth, or start with "gforth <file1> <file2> ...")
89: *.fi Forth image files (start with "gforth -i <image file>")
90: *.fb Forth blocks file (load with "use <block file> 1 load")
91: *.i C include files
92: *.ds documenation source
93: *TAGS etags files
94:
95: A number of Forth source files are included in this package that are
96: not necessary for building Gforth. Not all of them are mentioned in
97: the rest of the documentation, so here's a short overview:
