# Usage: check_source_count.py SEARCH_TERM COUNT ERROR_LOCATION REPLACEMENT [FILES...]
#   Checks that FILES contains exactly COUNT matches of SEARCH_TERM. If it does
#   not, an error message is printed, quoting ERROR_LOCATION, which should
#   probably be the filename and line number of the erroneous call to
#   check_source_count.py.
