Installation is simple since no compilation is necessary.
On a UNIX system with the make utility, you can install everything
by executing the command "make install" in this directory.
It will put everything in /usr/local. If you wish to use another
location, edit the Makefile. If you intend to install in
directories that you do not own, you will have to su first.

The rest of this is relevant only if you wish to install
by hand.

On a Unix-type system, just copy redet.tcl into a directory in
your path and mark it executable by giving the command:

chmod +x redet.tcl

You may wish to rename the program file "redet" to save typing.
The tcl/tk windowing shell wish must also be in your path.

Redet expects to find its reference manual in a directory
named RedetManual that is a sister to the program itself.
For instance, if you install the program itself as:

    /usr/local/bin/redet

Then the manual should be in the directory:

     /usr/local/bin/RedetManual

The files that must be copied to the RedetManual directory consist
of the manual web page itself, RedetManual.html, and the directory
RedetImages. You can copy the entire manual directory by means
of a command like:

cp -r RedetManual /usr/local/bin

Redet requires the use of a temporary directory in which it keeps
temporary files. In the absence of other information, Redet
will use the directory /tmp. If the environment variable TMP
is set, Redet uses its value as the temporary directory.
If TMP is not set but TEMP is set, Redet uses the value of TEMP
as the temporary directory.

If running under cygwin on Microsoft Windows, you may need to set
your TMP environment variable to "/cygdrive/c/tmp".

Please note that Redet does not itself execute regular expressions.
It merely provides an interface to various other programs.
It is up to you to see to it that the programs you wish to
have Redet execute are installed on your system and in your
path. The manual web page provides links to web sites from
which the supported programs may be obtained. Note, however,
that you can use tcl and tclglob without installing
any other program since Redet is written in Tcl and
in these two cases does execute the regular expressions
directly.

Similarly, Redet supports locales but can only make use
of the locales available on your system. You may need to
install additional locale files on your system in order
to use Redet in a particular locale.
