Documentation

The documentation for all LALSuite components is generated using Doxygen. The most recent LALSuite documentation from the nightly build can be found here.

The LAL Specification and Style Guide document (commonly known as the LAL Spec) contains the software specifications that code written for LALSuite should conform to. The most recent version of the LAL Spec can be found here.
