Installation


There are two ways to install Crema: You can either unzip crema.zip, or you can leave it zipped up. Which way is best for you depends on your Java environment and/or your own preferences.

Leaving crema.zip zipped up Unzipping crema.zip
This method reduces the clutter on your disk, but it requires you to modify your CLASSPATH.

This method is not suitable for Mac and SGI, because their Java environments cannot currently fetch classes directly from zip files.

  1. Put crema.zip in a safe place, for instance in the JDK's lib directory (next to classes.zip).
    .
  2. Append the full filename of crema.zip to your CLASSPATH environment variable, for instance:

    CLASSPATH=.;/jdk/lib/crema.zip

    It is not sufficient to list the directory in which crema.zip is located; you must include the filename!
This installation method is not as clean, but it works with any Java environment. And you may not need to modify your CLASSPATH.
  1. Create a new directory for Crema, or select a directory that is already on your CLASSPATH.
    .
  2. Unzip crema.zip in this directory. You should get one file, Crema.class, and two subdirectories, crema and coffee, containing more files.

    You may have to specify a commandline switch for your unzip utility (such as "-d" for PKUNZIP) to preserve the zip file's directory structure.
    .
  3. If you created a new directory in step 1, append it to your CLASSPATH environment variable, for instance:

    CLASSPATH=.;/crema

To verify your installation, run Crema with no parameters. Crema should repond with a summary of available command line parameters.
