Usage: ./run.sh [-d DEST] [-r CENTOS_RELEASE] [-p] [-n]

Builds a x86_64 RHEL binary release of Netdisco, including all CPAN
dependencies, netdisco-mibs and IANA OUI data

This is not meant to run Netdisco on RHEL, but merely to bundle all the
required files for isolated systems without Internet access

Provided as a courtesy to specific Netdisco users, if you wonder whether
you need this or not you probably don't


 -d DESTDIR (/opt/netdisco)
    Base directory of the install. Creates the following structure:
      DESTDIR/nd2 - Netdisco installation with all dependencies for RHEL
      DESTDIR/netdisco-mibs.tar.gz - MIBS
      DESTDIR/oui.txt - IANA OUI database

    A successfuly build will bundle DESTDIR into a tarball in the ./output
    directory of the host.

 -p include custom patches from the ./patches subdirectory
    Do not use this unless instructed to do so
