-    mpi.eclass:  Improve handling of unclassed dep strings
-    
-    Instead of requiring a list of packages to block when calculating the
-    dep list for an unclassed ebuild, simply inject a dep string.  This

-= Introduction =
-Empi is basically a reworking of vapier's crossdev script to
-handle installing multiple mpi implementations and applications
-that depend on them.  This is done through trickery involving
-adding categories that portage will recognize, moving mpi-enabled
-packages (defined as those using mpi.eclass) to a local overlay
-directory and then emerging these packages using the new
-category.
-
-Empi handles getting mpi application ebuilds into the overlay,
-copying anything in package.{use,keywords}, and wrapping the
-emerge process.  The eclass handles putting the package files
-into separate "root" directories based on the category name as
-well as making sure the applications build against the
-appropriate environment.
-
-I also provide eselect-mpi, which unlike every other eselect
-module I've ever used, is designed to manage a users personal
-environment by writing to ${HOME}/.env.d/mpi.  This provides a
-quick and easy way for users to experiment with various
-implementations while imposing on any other user's ability to
-use their preferred implementation.
-
-The newly written mpi.eclass should handle empi-based and standard
-emerging of packages in a manner that enables package maintainers
-to quickly port their applications without much knowledge of the
-underlying mechanics.  At least, that was my intent, maybe I
-succeeded.
-
-
-= Definitions =
-Class:  Fake category name used by empi.  Must be
-    prefixed with mpi-
-Base Implementation:  Actual mpi-implementation package that will
-    provide all mpi functionality to the above.
-
-
-= Instructions =
-
-The following creates a class called "mpi-openmpi"
-using sys-cluster/openmpi as the base implementation.  We also
-set some USE flags and make sure to unmask the appropriate
-version of sys-cluster/openmpi.  Long options and full package
-atoms are used, but not required.
-
-1.) Sync the science overlay.
-
-2.) Emerge empi
-
-3.) Setup /etc/portage/package stuff.
-    # echo ">=sys-cluster/openmpi-1.2.5-r1 pbs fortran romio smp" >> /etc/portage/package.use
-    # echo ">=sys-cluster/openmpi-1.2.5-r1" >> /etc/portage/package.keywords
-
-4.) Create the implementation.
-    # empi --create --class mpi-openmpi =sys-cluster/openmpi-1.2.5-r1
-
-5.) Add packages.
-    # empi --add --class mpi-openmpi hpl mpi-examples
-
-6.) Setup your user.
-    $ eselect mpi set mpi-openmpi
-    $ echo <<-EOF >> .bash_profile
-for i in $(ls ${HOME}/.env.d/*); do
-    source ${i}
-done
-EOF
-    $ source .bash_profile
-
-7.) Do stuff, or decide this is all worthless and cleanup the mess.
-    # empi --delete mpi-openmpi

-Actions:
-    ${GOOD}-c, --create${NORMAL} pkgspec        (Re)Initialize setup for mpi class.
-    ${GOOD}-a, --add${NORMAL} pkgspec(s)        Add packages using specified mpi class.
-    ${GOOD}-d, --delete${NORMAL} class          Remove everything related to specified class.

-Options:
-    ${GOOD}-C, --class${NORMAL} class           MPI class to use.
-    ${GOOD}-t, --tree${NORMAL} path             Path to portage tree to use ebuilds from.

-
-Notes:
-    ${HILITE}-${NORMAL} pkgspec is specified by a package string.  Without a version, the
