alias for apache.mk, since I don't see a reason why a package should
query the apache version without also adding a dependency on apache.
Fixed the documentation to match the code. Made the code simpler. Added
sanity checks for both package-settable and user-settable variables.
all PEAR packages to php?-pear-* and all Apache packages to ap13-* or
ap2-* respectively. Add new variables to simplify the Makefile
handling. Add CONFLICTS on the old names. Reset revisions of bumped
packages. ap-php will now depend on the default Apache and PHP version.
All programs using it have an implicit option of the Apache version
as well.
OK from jlam@ and adrianp@.
