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: i486-pc-linux-gnulibc1 (libc5)
14: i586-pc-linux-gnulibc1 (libc5)
15: i686-pc-linux-gnu (libc6)
16: alphaev56-unknown-linux-gnulibc1
17: alpha-dec-osf4.0b
18: mips-sgi-irix6.2
19: mips-dec-ultrix4.3
20: sparc-sun-sunos4.1.4
21: sparc-sun-solaris2.5.1
22: powerpc-unknown-linux-gnu
23: hppa1.1-hp-hpux10.20
24: i386-pc-cygwin32 (CygWin32 b18, Win95)
25: i386-pc-djgpp (DGJPP 2.0, MS-DOS 7.0 under Win95)
26: i386-pc-os2 (OS/2 3.0, EMX 0.9c)
27:
28: Read INSTALL for installation instructions, or INSTALL.DOS for DOS, Windows
29: 95, and OS/2. Mail bug-gforth@gnu.ai.mit.edu if you have problems. To start
30: the system, just say `gforth' (after installing it).
31:
32: You can find new versions of Gforth at prep.ai.mit.edu and its mirrors
33: or at
34:
35: http://www.complang.tuwien.ac.at/forth/gforth/
36: or
37: ftp://ftp.complang.tuwien.ac.at/pub/forth/gforth/
38:
39: The latter site contains binary distributions of Gforth for some
40: popular platforms.
41:
42: If you want to work on Gforth, mail me. Tasks to be done can be found
43: in ToDo; but if you would like to do something not mentioned there,
44: it's ok, too. In any case, we would like to hear what you are
45: doing. The most important tasks IMO are the missing ANS Forth words,
46: the documentation and the foreign language interface for C.
47:
48: On popular request, here are the meanings of unusual file extensions:
49:
50: *.fs Forth stream source file (include with "include <file>" from within
51: gforth, or start with "gforth <file1> <file2> ...")
52: *.fi Forth image files (start with "gforth -i <image file>")
53: *.fb Forth blocks file (load with "use <block file> 1 load")
54: *.i C include files
55: *.ds documenation source
56: *TAGS etags files
57:
58: A number of Forth source files are included in this package that are
59: not necessary for building Gforth. Not all of them are mentioned in
60: the rest of the documentation, so here's a short overview:
