A package is explicitely marked as unmaintained on
PEAR website
and you wish to take over as new Lead.
This short document will explain what steps you need to take.
The QA team will then state whether you can take over or not explaining why.
You should apply for a
PEARweb account
if you don't have one.
As a next step you will be added as new lead of the package.
In case you do not have a CVS account please
apply for one.
In any case you must send a mail to
PEAR Group
requesting cvs karma for the package.
It is important you mention you do so with the approval of the QA team.
If possible please add a link to the relevant QA list email,
using a mailing-list archive such as
GMane.
