There is no issue with having more than one function in a single oct
file. This was the last thing I meant to show you yesterday but didn't
had time. You can place all of your dolphin code in a single .cc file
and have it compiled into a single oct file.

What you will need to do then is tell Octave about it (see help text
for autoload). For a package, you can then either have a PKG_ADD file
at the root of the package (same directory where you have
DESCRIPTION), or you can have PKG_ADD comments on C+ the source (when
the package is installed, it will scan the source for this comments
and automatically generate the PKG_ADD file) [1].

For example, see the partint.cc file[2] in the miscellaneous
package[3] which defines both partcnt and partint. Here, a PKG_ADD
file is being used. I'd prefer to use PKG_ADD and PKG_DEL comments  on
the source but that's a choice left to the maintainer.
