Source Lines of Code
"Measuring programming progress by lines of code is like measuring aircraft building progress by weight"
Below is a rough count of the number of source lines of code contained within
the CSDMS model repository. Only models listed in the CSDMS model library
are included. In this estimate, a source line is considered as any line
that is not part of a comment, and is not blank. I have included SLOC
summaries by application, and by language.
