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 and DOS and should not be hard to port to other
10: systems supported by GCC. This version has been tested successfully on
11: the following platforms: i486-unknown-linuxaout, i586-unknown-linux,
12: alpha-dec-osf3.2, mips-dec-ultrix4.3, sparc-sun-sunos4.1.3_U1,
13: sparc-unknown-netbsd1.2 (configured with ac_cv_sizeof_long_long=0, see
14: INSTALL), hppa1.1-hp-hpux9.05, hppa1.1-hp-hpux10.20.
15:
16: Read INSTALL for installation instructions. Mail
17: bug-gforth@gnu.ai.mit.edu if you have problems. To start
18: the system, just say `gforth' (after installing it).
19:
20: You can find new versions of Gforth at prep.ai.mit.edu and its mirrors
21: or at

24: or
25: ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/
26:
27: The latter site contains binary distributions of Gforth for some
28: popular platforms.

30: If you want to work on Gforth, mail me. Tasks to be done can be found
31: in ToDo; but if you would like to do something not mentioned there,
32: it's ok, too. In any case, we would like to hear what you are
33: doing. The most important tasks IMO are the missing ANS Forth words,
34: the documentation and the foreign language interface for C.

36: On popular request, here are the meanings of unusual file extensions:
37:
38: *.fs Forth stream source file
39: *.fi Forth image files
40: *.fb Forth blocks file
41: *.i C include files
42: *.ds documenation source
43: *TAGS etags files

45: A number of Forth source files are included in this package that are
46: not necessary for building Gforth. Not all of them are mentioned in
47: the rest of the documentation, so here's a short overview:
