[newbie] Silly question - I don't know how to use man

[mendes]

Hello
        I know that this is a rather silly question but I definitely need help.
For instance, I installed procmail on my system.  The manuals were placed at
/usr/man/man1 and /usr/man/man5 as *.1.gz or *1.bz2 and *.5.gz or *.5.bz2.
When I type man procmail the sys returns no manual page for it. What am I
missing here?

        Thanks a lot.
