* New: In Hurricane::NetRoutingProperty, add and change the meaning
of the following flags:
- ManualGlobalRoute : now means that a global routing *trunk*
is present, made of "gmetalh", "gmetalv" & "gcontact".
- Manualdetailroute : added, get the former meaning of
ManualGlobalRoute, that is, the detailed routing is
already present for this net, but can be changed by the
detailed router. Implies that it respect the Terminal,
HTee & VTee structuration.
* New: Add Anabatic::Diskstra::loadFixedGlobal(), to account
a manually global net into the edges capacities.
* New: In Anabatic::Edges::ripup(), exclude manually global routed
segments from the ripup. Change the segment sorting function
so that thoses segments are put in head of list (considered
as "smaller").
* Change: In AnabaticEngine::setupPreRouteds(), now detect manual
global routed and manual detail routed signals, and tag them
accordingly.
* New: In AnabaticEngine::Configuration & Session, add proxies
for the global routing layers ("gmetalh", "gmetalv", "gcontact").
* New: In Anabatic::Constants, add flags for global fixed and
detail routed nets.
* Change: In KatanaEngine::updateEstimateDensity(), now use int64_t
for flute coordinates.
* New: Add CRL::RoutingGauge::hasLayer(), to know if a layer is
managed by the gauge (comparison by mask).

This package contains the following files:
flute.c -- The rectilinear Steiner minimal tree and wirelength estimation
algorithm described in the ICCAD 04 and ISPD 05 papers with
some improvements described in TCAD 07 paper.
flute.h -- The interface to use flute.
flute_mst.c -- The net breaking and merging techniques described in the
VLSIDAT 08 paper.
dist.[ch], dl.[ch], err.[ch], heap.[ch], mst2.[ch], neighbors.[ch],
global.h -- Utility functions used by flute_mst.c
POWV9.dat -- The lookup-table of optimal POWVs up to degree 9.
POST9.dat -- The lookup-table for optimal Steiner trees up to degree 9.
flute-net.c -- A program to evaluate the wirelength of a net. It takes
input from stdin as a list of points.
rand-pts.c -- A program to generate a list of random points.
flute-ckt.c -- A program to find FLUTE and half-perimeter wirelength
of a circuit in bookshelf format.
bookshelf_IO.[ch] -- Functions for flute-ckt.c to read bookshelf files.
memAlloc.[ch] -- Functions for flute-ckt.c to allocate memory.
ibm01/ibm01.* -- ibm01 bookshelf files that can be read by flute-ckt.c
license.txt -- License agreement.

To run the programs, first do a 'make'. POWV9.dat and POST9.dat is assume
to be in the current directory. Some example commands:
rand-pts | flute-net
rand-pts 20 | flute-net // 20-pin nets
rand-pts -r 20 | flute-net // randomized
flute-ckt ibm01 ibm01.aux ibm01/ibm01.pl
