   2 # updates php-pear .spec with Requires/Conflicts lines.
   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 #
  10 # To create completely new PEAR package spec, follow something like this:
  11 # $ pear download RDF-alpha
  12 # File RDF-0.1.0alpha1.tgz downloaded
  13 # $ pear make-rpm-spec RDF-0.1.0alpha1.tgz
  14 # Wrote RPM spec file php-pear-RDF.spec
  15 # $
  16 #
  17 # TODO: adjust similiarily noautoreqdeps
  18 # BUGS: the beta portions in version deps could be wrong (php-4.3.0b1 and alike)
  19 # see php-pear-DBA_Relational.spec
  20 # Something strange: Requires:  php-common < 4:3:5.1
  21 #
  22 # NOTE: old version of this script which was used to convert to new package format is in CVS branch MIGRATE.
