libctl is a free Guile-based library implementing flexible control files for scientific simulations. It was written to support our MIT Photonic Bands and Meep software, but has proven useful in other programs too.

libctl is free software under the GNU General Public license (GPL); see the license and copyright section of the manual for more information.

- Important: Most Linux distributions come with Guile already installed. Do not install your own version of Guile from source — having two versions of Guile on the same system will cause problems. However, by default most distributions install only the Guile libraries and not the programming headers — to compile libctl, you should install the "guile-devel" or "guile-dev" package (e.g. RPM) that came with your system.
- To have more control over the version of Guile to use, you can instead do
./configure GUILE=/path/to/guile GUILE_CONFIG=/path/to/guile-config
