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 and a powerful locals
4: facility, and it even has (the beginnings of) a manual. Gforth employs
5: traditional implementation techniques: its inner innerpreter is
6: indirect or direct threaded. Gforth is distributed under the GNU
7: General Public license (see COPYING).
8:
9: Gforth runs under Unix, Win95, OS/2, and DOS and should not be hard to
10: port to other systems supported by GCC. This version has been tested
11: successfully on the following platforms:
12:
13: checking host system type... alpha-dec-osf4.0d
14: checking host system type... alphaev56-unknown-linux-gnu
15: checking host system type... i486-pc-linux-gnulibc1
16: checking host system type... i686-pc-linux-gnu
17: checking host system type... mips-dec-ultrix4.3
18: checking host system type... powerpc-unknown-linux-gnu
19: checking host system type... sparc-sun-solaris2.5.1
20: checking host system type... sparc-sun-sunos4.1.4
21:
22: Read INSTALL for installation instructions, or INSTALL.DOS for DOS,
23: Windows 95, and OS/2. Mail bug-gforth@gnu.org if you have problems.
24: To start the system, just say `gforth' (after installing it).
25:
26: You can find new versions of Gforth at ftp://ftp.gnu.org/gnu/gforth/
27: and its mirrors or at
28:
29: http://www.complang.tuwien.ac.at/forth/gforth/
30: or
31: ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/
32:
33: The latter site also contains binary distributions of Gforth for some
34: popular platforms.

36: If you want to work on Gforth, mail me. Tasks to be done can be found
37: in ToDo; but if you would like to do something not mentioned there,
38: it's ok, too. In any case, we would like to hear what you are
39: doing. The most important tasks IMO are the missing ANS Forth words,
40: the documentation and the foreign language interface for C.
41:
42: On popular request, here are the meanings of unusual file extensions:
43:
44: *.fs Forth stream source file (include with "include <file>" from within
45: gforth, or start with "gforth <file1> <file2> ...")
46: *.fi Forth image files (start with "gforth -i <image file>")
47: *.fb Forth blocks file (load with "use <block file> 1 load")
48: *.i C include files
49: *.ds documenation source
50: *TAGS etags files
51:
52: A number of Forth source files are included in this package that are
53: not necessary for building Gforth. Not all of them are mentioned in
54: the rest of the documentation, so here's a short overview:
