   3 # the items are added randomly to the preamble, but once added their order is left intact.
   4 # it is still better than nothing. if somebody wishes to add sorting in this
   5 # script. i'd be just glad :)
   6 #
   7 # needs 'pear' for 'pear make-rpm-spec' command, ./builder for fetching sources.
   8 # You should have all PEAR packages installed to get best results (needed for epoch autodetection)
   9 # So far there are 3 packages with epoch > 0:
  10 # $ grep ^Epoch:.* php-pear-*.spec | grep -v 'Epoch:.*0'
  11 # php-pear-MDB2.spec:Epoch:               1
  12 # php-pear-MDB.spec:Epoch:                1
  13 # php-pear-PEAR.spec:Epoch:               1
  14 #
  15 # To create completely new PEAR package spec, follow something like this:
  16 # $ pear download RDF-alpha
  17 # File RDF-0.1.0alpha1.tgz downloaded
  18 # $ pear make-rpm-spec RDF-0.1.0alpha1.tgz
  19 # Wrote RPM spec file php-pear-RDF.spec
  20 # $
  21 #
  22 # TODO: adjust similiarily noautoreqdeps
  23 # BUGS: the beta portions in version deps could be wrong (php-4.3.0b1 and alike)
  24 # see php-pear-DBA_Relational.spec
  25 # Something strange: Requires:  php-common < 4:3:5.1
  26 #
  27 # NOTE: old version of this script which was used to convert to new package format is in CVS branch MIGRATE.
