[Build-common-hackers] Bug#332632: cdbs: pear.mk for building PHP Pear packages

[Charles Fry]

Package: cdbs
Version: 0.4.32
Severity: wishlist
Tags: patch

Please find attached a new make file sloted for addition at:

    /usr/share/cdbs/1/class/pear.mk

This file works for standard PHP Pear packages (the rough equivilant of
CPAN for PHP modules). This file itself was extracted from the
dh-make-php program which is currently the standard way to create Pear
packages. Once this is included in cdbs, dh-make-php can use it as well.
Note that I received direct feedback from the debian-webapps mailing
list regarding pear.mk, and have integrated all suggestions made there
by others.

cheers,
Charles
