# The following rule is not designed to be portable,

# 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.
#
# The second nm|grep checks for file-scope variables with `extern' scope.
