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 even has a
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, MacOS X,
12: OS/2, and DOS and should not be hard to port to other systems
13: supported by GCC. This version has been tested successfully on the
14: following platforms:
15:
16: i386-unknown-linux-gnu
17: x86_64-unknown-linux-gnu
18: i386-apple-darwin9.4.0
19: x86_64-apple-darwin9.4.0
20: ppc-apple-darwin9.4.0
21: i686-pc-cygwin
22: r8c (gforth-ec)
23:
24: Read INSTALL for installation instructions from source, or INSTALL.DOS
25: for DOS, Windows, and OS/2 from source, or INSTALL.BINDIST if you have
26: a binary package distributed as .tar.gz or .zip file. If you received
27: a self-installing executable, just run it and follow the instructions.
28:
29: To start the system, just say `gforth' (after installing it).
30:
31: You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
32: and its mirrors or at
33:
34: http://www.complang.tuwien.ac.at/forth/gforth/
35: or
36: ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/
37:
38: The latter site also contains binary distributions of Gforth for some
39: popular platforms.

41: If you want to work on Gforth, mail me. Tasks to be done can be found
42: in ToDo; but if you would like to do something not mentioned there,
43: it's ok, too. In any case, we would like to hear what you are
44: doing. The most important task IMO is the foreign language interface
45: for C.

47: On popular request, here are the meanings of unusual file extensions:
48:
49: *.fs Forth stream source file (include with "include <file>" from within
50: gforth, or start with "gforth <file1> <file2> ...")
51: *.fi Forth image files (start with "gforth -i <image file>")
52: *.fb Forth blocks file (load with "use <block file> 1 load")
53: *.i C include files
54: *.ds documenation source
55: *TAGS etags files
56:
57: A number of Forth source files are included in this package that are
58: not necessary for building Gforth. Not all of them are mentioned in
59: the rest of the documentation, so here's a short overview:
