A package using pkg-php-tools is initialized using dh_make (with dh7
rule format, now default). Usual cleaning is done (replacing all
boilerplate). Then debian/control and debian/rules are edited as
below (example with package php-foo). That's it!

====================
debian/rules:
<<<---
#!/usr/bin/make -f
%:
       dh $@ --buildsystem=phppear --with phppear
--->>>

====================
debian/control:
