listing functions in a package

[c.]

Hi,
Do you think it would make sense to have a command to
list all functions in a package as done by the attached patch?
This would be similar to the functionality of

help <toolbox name>

in matlab.
If this option was already available or you
do not find in useful please just ignore this message.

P.s. it's the first time ever I use mercurial,
so I wonder if this is the correct way to send patches

patch_pkg.changeset
