Due to Michael's recommendation I wanted to try out the 'dev' branch
version 1.5 of NHC and build an RPM package referred to by Michael.

Since I'm not a software developer, I had to figure out for myself the
detailed building steps - perhaps trivial to some of you, and stumbling
blocks to others.  This is what I came up with:

$ git clone https://github.com/mej/nhc.git
$ cd nhc
$ git switch dev              # Switch to the 'dev' branch
$ git status                  # Check the status
$ grep nhc_version configure.ac       # Verify the 'dev' version
m4_define([nhc_version], [1.5])
$ ./autogen.sh                # Undocumented build requirement
$ cd ..
$ mv nhc lbnl-nhc-1.5         # Rename the source folder
$ tar czf lbnl-nhc-1.5.tar.gz lbnl-nhc-1.5
$ rpmbuild -ta lbnl-nhc-1.5.tar.gz

The resulting RPM package is:

~/rpmbuild/RPMS/noarch/lbnl-nhc-1.5-0.82.gf8dc.el8.noarch.rpm

I've added those steps to my Slurm Wiki page:

Any comments?

Thanks,
Ole
