databases specified there. By default, the individual databases
are actually generated by forked children in this case, for
performance reasons. This feature can be switched off by new -f flag.
If the configuration file can't be parsed or doesn't contain any
_whatdb entries, the code falls back to /usr/share/man as before.
Added -C, which allows to specify alternate configuration file. This
is compatible with apropos(1) and whatis(1) flag of same name.
Update manpage accordingly and document behaviour a bit better.
Also add a HISTORY section, hopefully correct (done using CVS logs).
This solves toolchain/5231 by Tim Rightnour and bin/7696 by Allen Briggs.
