TreeView X is program to display phylogenetic trees on Unix-like platforms. It can read and display NEXUS and Newick format tree files (such as those output by PAUP*, ClustalX, TREE-PUZZLE, and other programs). It has a subset of the functionality of the version of TreeView available for the Mac Classic and Windows (it is roughly equivalent to version 0.95 of TreeView).

dxf2fig parses Autocad DXF input, then calls external routines to do either plotting or a fig conversion for xfig. The conversion is fairly complete. Layers (depths in xfig), blocks (compounds in xfig), colors, and linetypes are roughly preserved in the output file.

gSpiceUI is intended to provide a GUI for freely available electronic circuit simulation engines ie. NG-Spice and GNU-Cap. The utility gnetlist is used to convert schematic files to netlist files, Gwave or Gaw to display simulation results and gschem is the preferred schematic capture tool.

MeshLab is an open source, portable, and extensible system for the processing and editing of unstructured 3D triangular meshes. The system is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.

NETGEN is an automatic 3D tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. The connection to a geometry kernel allows the handling of IGES and STEP files. NETGEN contains modules for mesh optimization and hierarchical mesh refinement.

The Verilog-Perl library is a building point for Verilog support in the Perl language. It includes: * Verilog::Getopt which parses command line options similar to C++ and VCS. * Verilog::Language which knows the language keywords and parses numbers. * Verilog::Netlist which builds netlists out of Verilog files. This allows easy scripts to determine things such as the hierarchy of modules. * Verilog::Parser invokes callbacks for language tokens. * Verilog::Preproc preprocesses the language, and allows reading post-processed files right from Perl without temporary files. * vpassert inserts PLIish warnings and assertions for any simulator. * vppreproc preprocesses the complete Verilog 2001 and SystemVerilog language. * vrename renames and cross-references Verilog symbols. Vrename creates Verilog cross references and makes it easy to rename signal and module names across multiple files. Vrename uses a simple and efficient three step process. First, you run vrename to create a list of signals in the design. You then edit this list, changing as many symbols as you wish. Vrename is then run a second time to apply the changes.

Verilog-mode.el is a Verilog mode for Emacs which provides context-sensitive highlighting, auto indenting, and provides macro expansion capabilities to greatly reduce Verilog coding time. Recent versions allow you to insert AUTOS in non-AUTO designs, so IP interconnect can be easily modified. You can also expand Verilog-2001 ".*" instantiations, to see what ports will be connected by simulators.

CElvis is a clone of vi/ex, the standard UNIX editor. CElvis supports nearly all of the vi/ex commands, in both visual mode and colon mode. It also allows displaying and editing of documents using the Chinese GB (simple) and Big-5 (complex) encodings. Celvis is based on Elvis version 1.3 by Steve Kirkendall.

Have a TrueType font which is not recognized by X Window? Probably, the font uses an encoding other than Unicode! Open Type Organizer (oTo) can show you font info and add new 'name' and 'cmap' tables by translating the original ones.

This port installs four Chinese Big5/GB TrueType fonts, includes Kaiti/Mingti(Big5) and Kaiti/Sungti(GB). It then can be used along with X Window System or typesetting software like CJK. Thanks to Arphic Technology, you may freely distribute these high-quality fonts under a GPL-based license. See ARPHIC_*.TXT for details.
