Description from the author:
"This program will "compile" a rexx program in 2 main ways. It will tokenise the rexx (no 64K limit) or will simply wrap up the source (the default). The default action is to encrypt and compress the resultant image and attach it to an EXE stub. There are all sorts of options to control the stub, for example you can have a runtime DLL or standalone EXE. You can choose to have a compact EXE which will run in Warp onwards or a larger one which will also run in 2.0+. You can generate the stub as a PM program eliminating all the hassle of using 'RxMsgBox'."
