What if we supplied several sample .conf files, and let the user choose which 
to copy into the database directory?   We could have a "high read 
performance" profile, and a "transaction database" profile, and a 
"workstation" profile, and a "low impact" profile.   We could even supply a 
Perl script that would adjust SHMMAX and SHMMALL on platforms where this can 
be done from the command line.
