Building RPM files that are compatible with all possible Linux distributions
is a difficult task.  If a given RPM file that is downloaded from
http://www.cipherdyne.org/ is not compatible with your particular Linux
distro, then you can use the "cd_rpmbuilder" ("CipherDyne RPM Builder") to
build an RPM file for you on your own system.

The command line interface to cd_rpmbuilder is simple, and one command line
argument is always required "-p <project>" so that cd_rpmbuilder knows which
CipherDyne software project you want to build:

    # cd_rpmbuilder -p <project>

Note that cd_rpmbuilder is normally as root because it builds RPM's within
the /usr/src/redhat/ directory by default.  However, if you would like to
build as a normal user within a directory of your choosing you can do:

    # cd_rpmbuilder -p <project> -r <dir>

By default, cd_rpmbuilder builds the latest version of the specified project,
but if you want to build an older version, use the -b flag:

    # cd_rpmbuilder -p <project> -b <version>

If you want to see verbose output (including all output of the system
rpmbuild command), then use the -v flag:

    # cd_rpmbuilder -p <project> -v

Finally, here is some sample output for building the psad project available
at http://www.cipherdyne.org/psad/:

    # ./cd_rpmbuilder -p psad
