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: alpha-dec-osf4.0d
17: alpha-unknown-linux-gnu
18: alphapca56-unknown-linux-gnu
19: hppa1.1-unknown-linux-gnu
20: hppa2.0n-hp-hpux11.00
21: hppa2.0w-hp-hpux11.11
22: i386-unknown-freebsd5.1
23: i686-pc-cygwin
24: i686-pc-linux-gnu
25: mips-sgi-irix6.5
26: mipsel-pc-linux-gnu
27: powerpc-apple-darwin5.4
28: powerpc-unknown-linux-gnu
29: sparc-sun-sunos4.1.4
30: sparc-unknown-linux-gnu
31:
32: Read INSTALL for installation instructions from source, or INSTALL.DOS
33: for DOS, Windows, and OS/2 from source, or INSTALL.BINDIST if you have
34: a binary package distributed as .tar.gz or .zip file. If you received
35: a self-installing executable, just run it and follow the instructions.
36:
37: To start the system, just say `gforth' (after installing it).
38:
39: You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
40: and its mirrors or at
41:
42: http://www.complang.tuwien.ac.at/forth/gforth/
43: or
44: ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/
45:
46: The latter site also contains binary distributions of Gforth for some
47: popular platforms.

49: If you want to work on Gforth, mail me. Tasks to be done can be found
50: in ToDo; but if you would like to do something not mentioned there,
51: it's ok, too. In any case, we would like to hear what you are
52: doing. The most important tasks IMO are the missing ANS Forth words,
53: the documentation and the foreign language interface for C.
54:
55: On popular request, here are the meanings of unusual file extensions:
56:
57: *.fs Forth stream source file (include with "include <file>" from within
58: gforth, or start with "gforth <file1> <file2> ...")
59: *.fi Forth image files (start with "gforth -i <image file>")
60: *.fb Forth blocks file (load with "use <block file> 1 load")
61: *.i C include files
62: *.ds documenation source
63: *TAGS etags files
64:
65: A number of Forth source files are included in this package that are
66: not necessary for building Gforth. Not all of them are mentioned in
67: the rest of the documentation, so here's a short overview:
