c_count (classify and count lines of C or C++ source)

c_count counts lines, statements, other simple measures of C/C++
source programs. It isn't lex/yacc based, and is easily portable to a
variety of systems.

Note: By default, the binary and man page are installed as C_count
(uppercase C), to prevent a conflict with /usr/bin/c_count from the
SBo sloccount package. If you really want, you can run this script
with LOWERCASE=yes in the environment to install as c_count... but if
you do this, don't install sloccount on the same system.

c_count gives more detailed statistics than sloccount, but does not
include sloccount's person-years and cost estimates.

Example output from c_count:

$ C_count filename.c
  3656  1513   |filename.c
