Thanks for the info. It's added now.
I'm ashamed to say that I couldn't resist implementing -E option to
allow extended regexps. ;) The traditional and POSIX compliant basic
regexp is so hard to handle that you can't even say ".+\.S?o" but
"..*\.S{0,1}o".. (see re_format(7) for details)
Also, I revised the manpage to describe them in detail. Please check
it out:

I don't think I grasp your meaning.. GNU find(1)'s -regexp uses the
"basic regexp" that is _not_ the "extended regexp" which egrep(1) uses
nor the one perl(1) uses.
Anyway, here lists the facts:
- I implemented -regexp/-iregexp using FreeBSD's standard regex
library which is supposed to be compliant with POSIX.2
- The match is executed with REG_BASIC, which behavior is compatible
with GNU find(1) and NetBSD find(1)
- I, however, added -E so we can use extended regexp ;)
- Perl's regexp is known to be a unique variant that is different
from the "basic regexp" nor the "extended regexp" ;P

Me too. :)
