The MakeRPM script attempts to build RPMs of the
Lab::Measurement system.

Many of these actions are simply invoking Build (or Build.PL,
if it complains that things have changed).

First it finds the current version number of Lab::Measurement,
and updates perl-Lab-Measurement.spec with the current
version number.

Next, it updates the MANIFEST, then creates the
Lab-Measurement-(version).tar.gz archive file.

Finally, it runs rpmbuild with the .tar.gz archive
file to build both the installation and the source RPMS
in whatever your default "rpmbuild" directory is.

See documention on rpmbuild and set your $HOME/.rpmmacros %_topdir
appropriately for the directories where RPMs are build and
stored.
