Mapit is a program that reads in Judge output (either the response to a LIST command or the adjudicated moves / retreats / adjustments) and outputs a PostScript file which shows a map with units on (and arrows denoting moves). It will be useful only if you have a PostScript printer or software capable of displaying PostScript files on screen.
The Unix version, which needs to be compiled for your system (it comes with instructions, but you'll need the cc command) can be found here
How to add a variant to Mapit for Unix:
1) Locate your mapit directory (the one containing the other maps, such as regular.map.ps and regular.info).
2) Download the zip file into the mapit directory.
3) In a command shell, cd to your mapit directory, and unzip the zip file.
4) Rename the two files ((VARIANT).PS and (VARIANT).INF) to (variant).map.ps and (variant).info.
Example: for the Heptarchy maps:
Use your browser to download heptunix.zip into your mapit directory
Type at a shell prompt:
cd mapit (or wherever your mapit directory is)
unzip heptunix.zip (or whatever command your unzipper uses)
mv HEPTARCH.PS heptarchy.map.ps
mv HEPTARCH.INF heptarchy.info
The mv commands may be replaced by the appropriate operations in a graphical file manager, depending on your system.
Once this has been done, you can use the -v option of mapit to specify the variant, e.g. (if you use the dipmap script) cat (input filename(s)) | dipmap -v heptarchy
A program for unzipping files in Unix can be found here. This must be decompressed and untarred (most Unix systems should have the right commands available - check the manual pages for decompress and tar), and then compiled. If you do not have the C compiler cc with which to compile this utility, check here for unzip executables for various Unix platforms (see the README there for details). If you're still stuck, you'll have to find someone more knowledgeable - perhaps ask on an appropriate comp.* newsgroup.
