Here's some interesting project growth perspective. I finally finished
updating our enumeration script to reflect the changes to the build system and
file layout since moving to CMake. There were a variety of reasons why this
was needed, but the result is a particularly interesting comparison with the
state of our code from 8 years ago.
The file lists and tabulations are ever so slightly different, so care has to
be taken when comparing the numbers (e.g., header counts are now just credited
towards app or lib code), but the results are still interesting for big-picture
comparison purposes:

1550243 BRL-CAD Sources w/ Spaces
1369959 BRL-CAD Source Code Total
=========================================
The basic summary is that we've eliminated a few apps and added a ton of unit
tests (~75) and lots of library code (20% increase, +73k). The build system
and docs increased a bit (70% @ +13k and 13% @ 26k respectively) along with
scripting code (15% increase, +48k). The biggest growth was 3rd party code,
which has more than doubled (143% increase, +1.3M).
Overall, our source code has gone from 1.2M lines of code to nearly 1.4M with
our core compiled sources going from ~656k to ~746k (14% increase, +90k).
Cheers!
