This plugin provides the [[ikiwiki/directive/asymptote]]
[[ikiwiki/directive]] which allows embedding
[asymptote](http://asymptote.sourceforge.net/) diagrams in a page.

Security implications: asymptote has functions for reading files and
other dangerous stuff, so enabling this plugin means that everyone who
can edit your Wiki can also read any file from your hard drive thats
accessible to the user running Ikiwiki.

An example diagram:

[[!asymptote src="""
import geometry;
unitsize(1cm);
triangle t = triangle((0,0), (4,0), (0.5,2));
show(La="$D$", Lb="$E$", Lc="", t);
dot(t.A^^t.B^^t.C);
point pD = midpoint(t.BC); dot(pD);
point pE = midpoint(t.AC); dot(pE);
draw(pD--pE);

point A_ = (pD-t.A)*2+t.A; dot("$A'$", A_, NE);
draw(t.B--A_--t.C, dashed);
draw(t.A--A_, dashed);

point E_ = midpoint(line(t.B,A_)); dot(Label("$E'$", E_, E));
draw(E_--pD, dashed);
