- README for GNU ptx - last revised 91-10-10.
- Copyright (C) 1991 Free Software Foundation, Inc.
- See file COPYING for copying conditions.
-
- This is the 0.2 alpha release of `gptx', the GNU version of a
- permuted index generator. This software has the main goal of
- providing a `ptx' *almost* compatible replacement, able to handle
- small files quickly, while providing a platform for more development.
-
- This version reimplements and extends standard `ptx'. Among other
- things, it can produce a readable "KWIC" (keywords in their context)
- without the need of `nroff', there is also an option to produce TeX
- compatible output. This version does not yet handle huge input files,
- that is, those files which do not fit in memory all at once.
-
- *Please note* that an overall renaming of all options is
- foreseeable. In fact, GNU ptx specifications are not frozen yet.
-
- There is some documentation in `gptx.texinfo', but no man page.
- This software installs as two programs: gptx and ptx, which have
- different calling sequences and behaviour; ptx attempts to be
- compatible with UNIX ptx. Calling `gptx +help' or `ptx -h' prints an
- option summary.
-
- I tried to follow GNU installation standards. `gptx' has been
- tested on 386/ix, Appolo-3, Iris-4D, Sun-3 and Sparc systems. Tell me
- how it worked on your machine! To install, please follow these steps:
-
- 0. Only `gptx' will be compiled, and not `ptx', if the standard `ptx'
- default Ignore file is not found. So, if you also want `ptx' and the
- Ignore file is not /usr/lib/eign, be careful to define IGNOREFILE to
- the location of the Ignore file to use. You can do this while calling
- configure, as explained a little below.
-
- 1. At the top level (the directory this README is in), type
- `./configure'. This shell script attempts to guess correct values for
- various system-dependent variables used during compilation, and
- creates the files `Makefile', `lib/Makefile', `src/Makefile' and
- `doc/Makefile'. This takes a minute or two.
-
- If you want to compile in a different directory from the one
- containing the source code, `cd' to that directory and run `configure'
- with the option `+srcdir=DIR', where DIR is the directory that
- contains the source code. The object files and executables will be
- put in the current directory. This option only works with versions of
- `make' that support the VPATH variable. `configure' ignores any other
- arguments you give it.
-
- If your system requires unusual options for compilation or linking
- that `configure' doesn't know about, you can give `configure' initial
- values for variables by setting them in the environment; in
- Bourne-compatible shells, you can do that on the command line like
- this:
-
- $ CC='gcc -traditional' LIBS=-lposix ./configure
-
- 2. If you want to change the directories where the programs will be
- installed, or the optimization options, edit `Makefile' and change
- those values. If you have an unusual system that needs special
- compilation options that `configure' doesn't know about, and you
- didn't pass them in the environment when running `configure', you
- should add them to `Makefile' now. Alternately, teach `configure' how
- to figure out that it is being run on a system where they are needed,
- and mail the diffs to the address listed at the end of this file so we
- can include them in the next release.
-
- 3. In the top-level directory, type `make'. You don't need to
- otherwise touch the Makefiles in the subdirectories or use them
- directly.
-
- 4. If the programs compile successfully, type `make check'. There
- should not be any output from the `diff' program.
-
- 5. If everything went fine so far, type `make install' to install
- the programs and their documentation.
-
- 6. After you have installed the programs, you can remove the binaries
- from the source directories by typing `make clean'. Type `make
- distclean' if you also want to remove the Makefiles that `configure'
- created, for instance if you are going to recompile the utilities next
- on another type of machine.
