      ArgEnv
      Version 1.0.1
      Ronny Wichers Schreur
      ronny@cs.kun.nl
      The ArgEnv package provides a Clean interface to the command line
      arguments and the environment variables.
      This is the README for the Unix version. The Unix version has been
      tested on Solaris 5.5 and Clean 1.1 & 1.3, but it should work with all
      Unix versions with Clean 1.1 or better. To use the package with Clean
      version 1.1 you will have to make a few changes, which are documented
      in the source.

      variable
      USAGE
      To use the ArgEnv interface you have to link the object module that
      is created from the module ArgEnvC.c.
      If you use clm you should specify this extra object file with the -l
      option:
      % clm -l ArgEnvC.o <your-main-module>
      In the CleanIDE you can add this extra object file to the Object
      Modules section in the Options->Link Options dialogue.
      If you forget this, you will get the link error:
      Undefined first referenced
      symbol in file

      ArgEnvGetEnvironmentVariableC ArgEnv.o
      ArgEnvGetCommandLineArgumentC ArgEnv.o
      ArgEnvGetCommandLineCountC ArgEnv.o
      BUGS
      There is no way to stop the Clean run-time system from interpreting
      some of the command-line arguments.
