About CDSoft

CDSoft provides solutions for your IT problems:

• data converters (parsing, formatting, ...)
• data checkers (properties validations, ...)

using simple, fast, robust, portable and free technologies:

• portable and open source languages (for Unix, GNU/Linux, MS Windows, ...):
  • script languages: Python, Lua, ...
  • compiled languages such as C or C++ when performance is essential (but Lua for instance is already rather fast)
• portable and open source documentation format:
  • working format: reStructuredText
  • output format: HTML, PDF (or even reStructuredText)
  • automatic specification/design/code/test requirement coverage

We use only free and open source technologies and document formats to avoid maintenance and reuse problems:

• security (it is open source, you know what is inside)
• durability (it is open source, standard, commented and documented, you can understand how it is made and modify it)
