The PEAR Group occasionally
publishes so called Administrative Documents,
which describe the Group's decisions. You are expected to read
those documents before starting serious contributions to PEAR,
because they contain important information about the inner
workings of PEAR. The developers mailing list will be informed,
when new documents are added, so you do not need to visit the site
frequently.
This manual contains the Developer Guide, which provides
valueable information as well.
The Coding Standards describe the
standards which PEAR code must adhere to.
