# The following rule is not designed to be portable,
# and relies on tools that not everyone has.

# Most functions in src/*.c should have static scope.
# Any that don't must be marked with `extern', but `main'
# and `usage' are exceptions.  They're always extern, but
# don't need to be marked. Also functions starting with __
# are exempted due to possibly being added by the compiler
# (when compiled as a shared library for example).
#
# The second nm|grep checks for file-scope variables with `extern' scope.
