Installing A.P.E.
The only thing you need to "install" for A.P.E. is dparse, the APE compiling utility.
If you unzipped the tools zip correctly, you should find ION Radiant in the
\tools\Ape\
directory.
That's it, pretty painless. :) Included with dparse is d.bat. To compile an APE file, go to the command prompt, change dir to
the directory you keep your ape source files in, (should be the same directory darse.exe, and d.bat are in) and type
d apefilename
