1Installation is simple since no compilation is necessary. 2On a UNIX system with the make utility, you can install everything 3by executing the command "make install" in this directory. 4It will put everything in /usr/local. If you wish to use another 5location, you may set DESTDIR, PREFIX, BINDIR, etc. macros just as 6for most Open Source packages. For example, to install Redet into 7/usr instead of /usr/local, simply run: 8 9make install PREFIX=/usr 10 11To install into your home directory (you will not need superuser 12access to install this way), run: 13 14make install PREFIX=$HOME 15 16If you intend to install in directories that you do not own--such as 17the default /usr/local--you will have to su first. 18 19Under Mac OS X the command: 20 21make macosx_app 22 23should install everything in the correct locations. 24 25 26The rest of this is relevant only if you wish to install 27by hand. 28 29On a Unix-type system, just copy redet.tcl into a directory in 30your path and mark it executable by giving the command: 31 32chmod +x redet.tcl 33 34You may wish to rename the program file "redet" to save typing. 35The tcl/tk windowing shell wish must also be in your path. 36 37Redet expects to find its reference manual in the 38/usr/local/share/Redet/Manual directory (or 39$PREFIX/share/Redet/Manual, if you set PREFIX manually above). 40 41The files that must be copied to the RedetManual directory consist 42of the manual web page itself, RedetManual.html, and the directory 43RedetImages. You can copy the entire manual directory by means 44of a command like: 45 46mkdir /usr/local/share/Redet && cp -r Manual /usr/local/share/Redet 47 48Redet requires the use of a temporary directory in which it keeps 49temporary files. In the absence of other information, Redet 50will use the directory /tmp. If the environment variable TMP 51is set, Redet uses its value as the temporary directory. 52If TMP is not set but TEMP is set, Redet uses the value of TEMP 53as the temporary directory. 54 55If running under cygwin on Microsoft Windows, you may need to set 56your TMP environment variable to "/cygdrive/c/tmp". 57 58Please note that Redet does not itself execute regular expressions. 59It merely provides an interface to various other programs. 60It is up to you to see to it that the programs you wish to 61have Redet execute are installed on your system and in your 62path. The manual web page provides links to web sites from 63which the supported programs may be obtained. Note, however, 64that you can use tcl and tclglob without installing 65any other program since Redet is written in Tcl and 66in these two cases does execute the regular expressions 67directly. 68 69Similarly, Redet supports locales but can only make use 70of the locales available on your system. You may need to 71install additional locale files on your system in order 72to use Redet in a particular locale. 73 74
