Checking whether RCS is in your path (Unix Only)

The filebrowser example comes with an RCS repository. This tutorial relies on RCS 5.7 which is supplied together with the SNiFF+ package and is installed from there.
To check whether the correct version of RCS is in your path:

  1. Open a Unix shell.
  2. Enter % rcs -V1 at the command prompt.
    You will receive one of the following outputs:
    • rcs error: -V1 out of range 3..5
    This shows that the correct version of RCS is installed.
    • rcs error: Unknown option: -V1
    This shows that an old, unusable version of RCS is installed. If you get this output, please install RCS 5.7 to execute the version control steps in the next chapter.
