For every package you should start a proposal in PEPr
as a draft to initiate dicussion on the developers mailing list.
By discussing the package with the PEAR developers you will
easily be able to find out if:
there are technical issues with the package/code
a package with similar functionality already exists
there are people working on something similar, so you can join
forces
etc.
By reading between the lines, you should also be able to find out
if you will be able to gather enough positive votes in the formal
proposal process.
Be aware that people will scrutinize your code, so be prepared for
criticism (both positive and negative) and save everybody a bunch
of time by making sure your scripts adhere to the Coding Standards.
Please note that PEAR is an international project. People come from
different cultural backgrounds where english may not be their native
tongue. Misunderstandings may happen because of that, so assume
the person is trying to do good. Do not worry if your
English is not perfect but do try to be as clear as possible and do
not hesitate to ask for advice.
