Yes, this is what makes Chirp so great. Take a look at this file for example:

http://chirp.danplanet.com/projects/chirp/repository/entry/chirp/ic2200.py

It starts out with a memory definition, which you'll find familiar to c structs.

Later you'll see @directory.register. This tells Chirp that the
following class is a new radio to support.

class IC2200Radio(icf.IcomCloneModeRadio, chirp_common.IcomDstarSupport)

This is the basic class definition for a radio. In here you will write
all the code specific to this model. Notice that no code here writes
to the serial port. This is because the IC2200 shares a clone protocol
with most (all?) other Icoms. These features are provided by
IcomCloneModeRadio, and you don't need to rewrite them (unless your
model uses a different protocol).

The important methods you will need to write for your radio are
get_features(), get_memory(), and set_memory(). Here you translate the
radio-specific data into something Chirp's GUI can understand.

No, Mercurial. More information here:

the devel mailing list for development discussions like this.
