   5 # revdep-rebuild: Reverse dependency rebuilder.
   6 # Original Author: Stanislav Brabec
   7 # Current Maintainer: Paul Varner <fuzzyray@gentoo.org>
   8
   9 # Known problems:
  10 #
  11 # In exact ebuild mode revdep-rebuild can fail to properly order packages,
  12 # which are not up to date.
  13 # http://bugs.gentoo.org/show_bug.cgi?id=23018
  14 #
  15 # Rebuilding using --package-names mode should be default, but emerge has no
  16 # feature to update to latest version of defined SLOT.
  17 # http://bugs.gentoo.org/show_bug.cgi?id=4698

  19 # Customizable variables:
  20 #
  21 # LD_LIBRARY_MASK - Mask of specially evaluated libraries
  22 # SEARCH_DIRS - List of directories to search for executables and libraries
  23 # SEARCH_DIRS_MASK - List of directories to not search
  24 #
  25 # These variables can be prepended to either by setting the variable in
  26 # your environment prior to execution, or by placing an entry in
  27 # /etc/make.conf.
  28 #
  29 # An entry of "-*" means to clear the variable from that point forward.
  30 # Example: env SEARCH_DIRS="/usr/bin -*" revdep-rebuild will set SEARCH_DIRS
  31 # to contain only /usr/bin
