For that matter how many know about 'apropos'? And, even if they do, they may not discover 'locate' because 'apropos search' doesn't find either 'updatedb' or 'locate'. You have to enter 'apropos find' to discover that 'locate' exists, and even then you could get side tracked into trying to use the much more complex 'find' utility.
Or the old-school rpm: $ rpm -ql spamassassin|grep TxRep /usr/share/man/man3/Mail::SpamAssassin::Plugin::TxRep.3pm.gz /usr/share/perl5/vendor_perl/Mail/SpamAssassin/Plugin/TxRep.pm Dave
