MetaPostThis module provides some useful routines to help MetaPost users
migrate old MetaPost code to Asymptote. Further
contributions here are welcome.
Unlike MetaPost, Asymptote does not implicitly solve
linear equations and therefore does not have the notion of a
whatever unknown. The routine extension (see extension)
provides a useful replacement for a common use of whatever: finding the
intersection point of the lines through P, Q and
p, q. For less common occurrences of whatever, one
can use the built-in explicit linear equation solver solve instead.
