ablfs-more legacy trunk
Last change on this file since c048987 was 2140f22, checked in by Pierre Labastie <pierre@…>, 7 years ago

New management of dependencies:

  • Even if only required or recommended deps only are requested and built, account for optional deps to build the pacakge order
  • build "runtime" deps after the pacakge dependening on them, but before any other package
  • using the "first" role in the book, implement pass1 pacakges when there are circular dependencies
  • Documentation has still to be written
  • There must be bugs, thank you for testing...
  • Property mode set to 100644
