The hash %INC contains entries for each filename included via the
use operators. The key is the filename
you specified (with module names converted to pathnames), and the
value is the location of the file found. The
operator uses this hash to determine whether a particular file has
already been included.
If the file was loaded via a hook (e.g. a subroutine reference, see for a description of these hooks), this hook is by default inserted into %INC in place of a filename. Note, however, that the hook may have set the %INC entry by itself to provide some more specific info.
