The present version of Nmap has an undocumented $NMAPDIR environmental
variable you can set.  Nmap will look in that directory first for
nmap-services, nmap-protocols, nmap-rpc, and nmap-os-fingerprints.  ny
files not found there, are searched for in ~/nmap, and then a
compiled-in location such as /usr/share/nmap .  As a last resort, Nmap
will look in the current working directory.

While the environmental variable can be easily used to set
per-nmap-execution service files, I agree that command line options
are often more convenient.  So I just added a --datadir option for the
next version of Nmap.  That option has even higher priority than the
environmental variable.  I also documented it this time.

I hope to release the next version tonight or tomorrow.

Cheers,
