cvs -d:pserver:anonymous@cvs.sv.gnu.org:/sources/qhull co debian qhull

Moved debian directory two levels down from above qhull (..) to project/
It will need updating for its new location.

Placed all Makefile-am files in config/

This is a maintenance release done by Rafael Laboissiere <rafael@debian.org>.
 - src/rbox.c (main): Avoid problems of evaluation order when
   pre-incrementing arguments of strtod
 - src/io.c (qh_produce_output), src/stat.c (qh_initstatistics): Use %lu
   instead of %d in the format string for arguments of type size_t
 - html/qhull.man, html/rbox.man: Fix several syntax, macros, and hyphen
   problems in man pages
 - The Autotools files have been generated with modern version of autoconf (2.63),
   automake/aclocal (1.10.2), and libtool (2.2.6)
 - Some character issues in the man pages are fixed

New Features:
 - Add Maple output ('FM') for 2-d and 3-d convex hulls [T. Abraham]

Breaking Code Changes:
 - Annotate C code with 'const'.  An ANSI compatible compiler is required.

Bug Fixes and Code Changes:
 - Fixed qh_findbest() for upperdelaunay facets w/o better, lower neighbors
     For library users and some qhull users [A. Cutti, E. Milloti, K. Sun]
 - Preserved qhmem.ferr in qh_memfreeshort() for library users
 - Removed 'static' from qh_compare... for io.h and merge.h [V. Brumberg]
 - Split out qh_initqhull_start2() to avoid allocating qh_qh
 - Split out qh_freeqhull2() to avoid freeing qh_qh
 - Split out qh_produce_output2() and qh_prepare_output()
 - qh_initstatistics() frees a previously existing qh_qhstat
 - qh_initqhull_start2() checks that qh_initstatistics() called first

Documentation:
 - Add warning to findDelaunay() and qh_in.htm about tricoplanar facets
 - Noted Edelsbrunner's Geometry & Topology for Mesh Generation [qh-impre.htm]
 - Noted Gartner's Miniball algorithm [qh_impre.htm]
 - Noted Veron and Leon's shape preserving simplification [qh_impre.htm]

qhull 2003.1  2003/12/19

Bug Fixes:
 - Reversed coordinate order for qh.ATinfinity in qh_projectinput [V. Brumberg]
   This effects:
     Qhull library 'd' or 'v' users with 'Qz' and unequal coordinate ranges.
     qdelaunay/qvoronoi users with 'Qbk:0Bk:0', 'Qz', and unequal coordinate ranges

Changes to code:
 - Replaced qh_VERSION with qh_version in global.c [B. Pearlmutter]
    The previous techniques were either clumsy or caused compiler errors
 - Removed unused variables from qh_findbest and qh_findbestnew [B. Pearlmutter]
 - Note that qh.TESTpoints was added in 2002.1 for tsearch implementation

Changes to distribution:
 - Added Unix distribution including Debian files [R. Laboissiere]
    The previous Unix distribution is now the source distribution
 - Added rpm distribution [L. Mazet]
 - Investigated generation of Win32 dll.  Need to define a C++ interface.

Changes to documentation:
 - Moved Qhull to www.qhull.org (geom.umn.edu is not available)
 - The Geometry Center is archived at http://www.geom.uiuc.edu
 - Reviewed introduction to each program
    Triangulated output ('Qt') is more accurate than joggled input ('QJ')
    qdelaunay is 'qhull d Qbb' [C. Ulbrich]
    qvoronoi is 'qhull v Qbb'
    Added example of non-simplicial intersection to halfspace intersections
 - Added warning about using the Qhull library.
 - Added qhull timings to When to use Qhull [C. Ulbrich]
 - Reorganized the home page index and the manual index
 - Moved qh-home.htm to index.htm

Changes to examples
 - Fixed options for eg/eg.t23.voronoi.imprecise [B. Pearlmutter]

Changes to distribution:
 - Set up savannah.nongnu.org/projects/qhull/ [R. Laboissiere]
 - Set up www.thesa.com as a backup
 - Added qh-get.htm, a local copy of the download page
 - Added Visual C++ interface to Qhull, qhull_interface.cpp [K. Erleben]
 - Use HTTP instead of FTP for downloading Qhull
 - Renamed qhull-1.0.sit.hqx

Bug fixes:
 - Fixed sign of coefficients for cdd halfspaces ('FD','Fd')  [T. Abraham]

Changes to code:
 - Replace qh_version with qh_VERSION in qhulllib.h.
   Allows shared libraries and single point of definition
 - Added qh.TESTpoints for future implementation of tsearch

Changes to build
 - Makefile.txt works under cygwin
 - Added Make-config.sh to create a Debian build [R. Laboissiere]
 - Added .exe to Makefile.txt#clean.
 - In README, use -fno-strict-aliasing with gcc-2.95.1 [Karas, Krishnaswami]
 - Fixed chmod in Makefile.txt [B. Karas]

Documentation updates
 - Documented input options for each program [A. Montesinos]
 - FAQ: "How to get the radii of the empty spheres for Voronoi vertices"

URL updates:
 - Changed official URL from locate/qhull to software/qhull
 - Changed URLs from relative to absolute in qh-home.htm and qh-get.htm
 - Added URL for Newsgroup: comp.soft-sys.matlab
 - Added URL for GNU Octave
 - Added URLs for Google and Google Groups
 - Replaced qhull_mail.html and qhull_bug.html with mailto links.
 - Removed URL for Computational Geometry Tribune
 - Changed URL for locate/cglist to software/cglist
 - Used site relative links for qh-home.htm
