Description:
library for flexible control files, documentation
libctl is a free Guile-based library implementing flexible control files for scientific simulations. It was written to support the MIT Photonic-Bands program, but will hopefully prove useful in other programs too. . This package contains the documentation in HTML format and a simple example of how to use it.
