This probably won't make it to the list, as my mail is still rejected.

I have been working on some maxima first order ODE routines using the 
approach in the papers below, and Zimmerman's handbook.  I have "working"
routines for Clairault, Lagrange and Riccati equations and have made
limited progress on Lie group methods.

The routines for Clairault, Lagrange and Riccati equations are probably
ready for review.
