ITP: graphviz
http://www.graphviz.org/
So, this package includes a big wad of different things, several of
which could probably do fine on their own. Does anyone see the best
way to split this up? Maybe -programs, gdtclft, -graphfunctions?
------
What is it?
GraphViz provides a number of programs and Tcl extensions:
Programs
dotneato
(dot and neato in a single executable) A batch layout tool for directed and undirected graphs. The Input is a description of the graph in the dot language and the
output is a rendering of the graph in a choice of vector or bitmap graphics formats.
lefty
A two-view graphics editor for technical pictures.
dotty
A lefty script for directed graphs
lneato
A lefty script for undirected graphs.
Tcl Extensions
Tcldot
The batch layout capabilities of dotneato
Gdtclft
Tcl functions for drawing to bitmaps in various formats (png, jpeg, ...) using Tom Boutell's gd and TrueType font rendering from FreeType. This code is used by the
renderers in Tcldot, but the package can also be used independently.
Tkspline
A small extension to add bezier-spline smoothing methods to Tk. Supports the edge routing algorithms used by Tcldot.
Tcldgr
Functions for the incremental manipulation of graph data structures.
Tcldgl
Incremental Layout engines for graphs. Designed for use with Tcldgr, but can also be used independantly.
Tclpathplan
Functions for computing shortest paths around polygon obstacles.
------
Also, there is probably a licensing problem, they seem to use the
Lucent license. If this is the same one that Plan 9 uses, I guess
this stuff goes in non-free:-(

BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, (b) ANY CLAIM
ATTRIBUTABLE TO ERRORS, OMISSIONS, OR OTHER INACCURACIES IN THE SOURCE

independently negotiating for necessary rights from the third party.
4. You acknowledge that the Source Code and Capsule may be subject to U.S. export
laws and regulations, and, accordingly, you hereby assure AT&T that you will not,
directly or indirectly, violate any applicable U.S. laws and regulations.
5. Without limiting any of AT&T?s rights under this Agreement or at law or in equity, or
otherwise expanding the scope of the license and rights granted hereunder, if you
fail to perform any of your obligations under this Agreement with respect to any of
your Patches or Derived Products, or if you do any act which exceeds the scope
of the license and rights granted herein, then such Patches, Derived Products
and acts are not licensed or otherwise authorized under this Agreement and such
failure shall also be deemed a breach of this Agreement. In addition to all other
relief available to it for any breach of your obligations under this Agreement, AT&T
shall be entitled to an injunction requiring you to perform such obligations.
6. This Agreement shall be governed by and construed in accordance with the laws of
the State of New York, USA, without regard to its conflicts of law rules. This
Agreement shall be fairly interpreted in accordance with its terms and without any
strict construction in favor of or against either AT&T or you. Any suit or proceeding
you bring relating to this Agreement shall be brought and prosecuted only in New
York, New York, USA.
