we use the gentoo-devhelp list for this stuff

use the distutils eclass ?  see if it has a setup.py or something like that.

the description is generally a sentence fragment, so drop the period at the end

don't leave uncomment URLs in there

generally we default to ~amd64 ~x86.  especially since you said this
is python code and not compiled.

mucking with source tree layout is generally a src_unpack operation

use ":" as your separator and you wan't have to escape all of the
forward slashes.

when dealing with long lines, it's customary to wrap it like so:
    sed -i \
        <-e option> \
        <-e option> \
        path/to/file || die

also, there's no need to add a message to `die` here since the PM is
smart enough to show you the snippet of code that failed as well as
the line number

i think once you convert to distutils, much of this will go away.
i'll respond just to give you an idea of how to do things in general.

there's no need for these dodir's as the doins and such helpers will
automatically create the required directories

when you use variables, you need to do "local i" so you don't
clobber/export them unintentionally

i imagine the `find` could be replaced with: src/*.py

>		doins $i

need to use "|| die" when using `doins`
