Setting up PC-Choices

    Copy pcc.zip to the PC, say to the root directory on the C drive (c:\).
    You should have an UNZIP utility that unpacks ZIP archives.  (Contact
    lup@cs.uiuc.edu if you don't.)  Unpack pcc.zip with your UNZIP utility
    like this:

        unzip -d pcc.zip

    (Note: Some old versions of PKUNZIP are buggy and will complain about
    about CRC errors when there are really none.  Use the newest version of
    PKUNZIP or use Info-ZIP's UNZIP instead.)

    The directories pcc, pcc\bin and pcc\cbin and their files will be
    unpacked in the current directory.  Delete pcc.zip.  (If a previous
    version of PC-Choices is already installed on your machine, UNZIP
    will ask you whether it should overwrite the files; just say "yes".)

    We now have to edit pcc\bin\profile to tell the command shell
    (Chocs) where to look for the Choices application binaries.  Edit
    pcc\bin\profile and you will see this:

        PATH=d:/pcc/cbin

    Change it so that it references the correct directory.  For example,
    if you unpacked the PC-Choices package in c:\, you should change
    the line above to:

        PATH=c:/pcc/cbin

    If your PC is an IBM PS/2, PS/55 or something similar, edit
    c:\pcc\bin\config, change "PS2Keyboard = no" to "PS2Keyboard = yes",
    and change "PS2Timer = no" to "PS2Timer = yes".

    PC-Choices is now ready to be used.  See the file pcc\doc\pccdoc2
    for instructions.
