LibreDWG was based on LibDWG (http://libdwg.sourceforge.net), which is written with variable names, documentation and comments in Esperanto.

There are also cmdline tools and libraries to read and write DWG files, with converters for various formats: DXF, DXFB, SVG, PS, JSON, XML, ....
and a SaveAs functionality, to convert between the various DWG versions.
It can read r13-r2018 DWG, write r13-r2000 DWG, write r11-r2018 DXF ascii and binary. Much more object types than any other free DWG library.

I've setup continuous integration testing for all branches and pull requests at https://travis-ci.org/LibreDWG/libredwg/builds for GNU/Linux, and at https://ci.appveyor.com/project/rurban/libredwg for windows, which also generates binaries (a dll) automatically. ...

New hackers' wiki

In an attempt to build a tool to assist development, with developers focused documentation like compiling, testing, sending patches and whatever we think might be useful, I've created the LibreDWG hackers' wiki, hosted at LibrePlanet: http://groups.fsf.org/wiki/LibreDWG. Feel free to contribute as well.
