The package is a small set of macros for drawing direction fields, phase portraits and trajectories of differential equations and two dimensional autonomous systems. The Euler, Runge-Kutta and 4th order Runge-Kutta algorithms are available to solve the ODEs. The picture is translated into mfpic macros and MetaPost is used to create the final drawing. The package is was designed for use with LaTeX, but it can be used in plain TeX as well. Online demonstration of the mfpic4ode macros is available on the Mfpic Previewer as Example 6.
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
