Personalities/Java compiler
INSTALLATION NOTES
VERSION 0.1.10
December 4, 1998
===========================

What you need:
  - pjc-<version>.<fmt>
     where <version> is the version of the PJC compiler you
                     are trying to install
                       (i.e. 0_1_10)
           <fmt>     is one of the compression formats 
                     supported (i.e. zip, jar, gz, Z)

  - Demeter/Java's demjava.jar runtime library. 
     make sure you have demjava.jar installed and it isa
     accesible by the java interpreter.



Unix installation:
 (1) Uncompress the pjc-<version>.<fmt> file in the 
     directory where you want the PJC compiler to live. For
     example, if you want to install the compiler on the
     /user/local/  subtree, and the file is in the 'compress'
     format (.Z) then you would do something like:
        $ cd /tmp
        $ uncompress pjc-0_1_10.tar.Z
        $ cd /user/local
        $ tar xvf /tmp/pjc-0_1_10.tar

     This step will create the appropriate PJC subtree 
     (/usr/local/pjc-0_1_10 in our example). This directory
     is then the PJC_HOME directory.

 (2) Add
        ${PJC_HOME}/bin
     to your PATH set, so that you can run the 'pjc' script
     from anywhere in the filesystem.

 (3) Modify
        ${PJC_HOME}/bin/pjc
     to update the definition of the PJC_HOME variable.


Windows installation:
 (1) Uncompress the pjc-<version>.<fmt> file into the 
     directory you want this version of PJC to live. Use
     any of the more popular utilities, such as WinZip
     (from http://www.winzip.com) to uncompress and install.
   
     For example, if you would like PJC to live under the
     C:\ directory, simply extract the file onto C:\ and
     the appropriate PJC directory (and subdirectories)
     should be generated. In our example, you would get
     C:\pjc-0_1_10. This directory is now referred as
     PJC_HOME
  
 (2) Add %PJC_HOME%\bin to your PATH environment variable 
     so you can access the 'pjc.bat' script from wherever
     in the filesystem. Depending on your operating system,
     there are two ways to do this:
      - Windows 95/98: modify you C:\AUTOEXEC.BAT file and
        add the following line
               PATH=%PATH%:<pjc-home>\BIN
        where <pjc-home> is the full description of the 
        PJC_HOME directory. Continuing with our running
        example, you would add the following line:
               PATH=%PATH%:C:\PJC-0_1_10\BIN
      - Windows NT: Select 'Start', 'Settings', 
        'Control Panel', 'System', and then click on the 
        'Environment' tab. Find the PATH variable definition
        in the "User Variables" section of the dialog box
        and add the PJC_HOME's bin directory, as explained
        in the Windows 95/98 section.

 (3) Edit %PJC_HOME%\bin\pjc.bat to update the definition
     of the PJC_HOME (and DEMJAVA_HOME if applicable) 
     variables. In our example, you would modify pjc.bat
     to read:
        @set PJC_HOME=C:\PJC-0_1_10


Testing the installation:

After installing PJC, make sure you refresh the environment
as required by your operating system and then try typing
  pjc
at the command prompt. You should see the PJC banner. If you
don't make sure your PATH variable is set properly.
