Quick fix to apply Metis to the Mandriva use case (wordpress+varnish deployment)
now Metis uses ExtLib instead of Batteries (uniformity with Zephyrus + bugfix)
first attempt at printing out abstract plan in DOT format
now we output DOT file enriched with clusters
jsut some minor changes
eliminated spurious dependency on Ocamlgraph library + some work for conditional compilation
now Makefile supports conditional compilation (by preprocessing with camlp4)
modified a few scripts to work with the new invocation syntax
now -ap argument (abstract plan) is really optional
minor changes
added new input specification + some minor changes
use case with 3 instances of Wordpress modified by hand
modified source code for textual output to comply with VERBOSE macro (for debugging)
now blue arrows in the abstract plan are in bold style
fixed script testB_5.sh for abstract plan generation
finished removing printing debug info on stdout
added doc target into Makefile for ocamldoc compilation
finally merged the mandrivaUseCase branch into master
