This is an initial take at renaming the project to Monitoring Plugins.
It's not expected to be fully complete, and it is expected to break
things (The perl module for instance). More testing will be required
before this goes mainline.
Use sendmail(8) instead of mail(1) in order to be able to set the
"Content-Type" header field on systems where the available mail(1)
command doesn't allow for setting it. This makes the "-H" flag (cf.
commit 71350c5a) unnecessary.
Now that we moved our Git repositories to SourceForge, we don't need to
maintain local clones for generating commit notifications anymore, as
SourceForge provides shell access to the repositories. Instead, we now
run git-notify as a post-receive hook on the SourceForge server.
Actually, we use a wrapper which executes git-notify with the desired
options and which makes it easy to add other post-receive hooks in the
future.
