It does a string substitution of a line that contains "head-pattern".
That looks like an error since who would search for a line starting with
"head-pattern"? The () is meant to encapsulate a substitution pattern
to be used in the replacement string but they aren't doing that.
use ($1) would include whatever module is passed as the first argument.
This fragment is incomplete and makes no sense. The OP will have to
explain what they want because this is complete crap.
