-This version of par2cmdline has been compiled and tested on the following
-compilers and operating systems:
-
-  MS Visual Studio.NET  on  Windows XP
-  gcc 3.2               on  CygWin 1.3.22
-  gcc 3.2.2             on  Red Hat Linux 9.0
-
-If you wish to compile par2cmdline under a different environment, then you
-should start by trying to compile with the supplied Makefile.
-
-If you get compile errors, then the most likely place you will need to make
-changes will be in par2cmdline.h, diskfile.h, and diskfile.cpp.
-
-See the file ROADMAP for details of what each of the source files is used for.
-
-If you successfully port par2cmdline, it would be appreciated if you could post
-the details on the parchive web site at http://sourceforge.net/parchive.
