Counts number of lines (in source code excluding comments)
I took java to make the find command simpler and to state that it works for any language supported by cpp. cpp is the C/C++ preprocessor (interprets macros, removes comments, inserts includes, resolves trigraphs).

The -L 1 option tells xargs to launch one process for each line, indeed cpp can only process one file at the time...
