Dear admb,
There is a bit of html in your example:
http://admb-project.org/community/tutorials-and-examples/mark-recapture-random-effects-model
It has < where you should have <.  It seems easy to fix and would 
make the example more useful
to people who are just starting out.

For example, I would like to use my ADMB fitting engine to fit e.g. a gaussian in time, and compare this to a fit with a gaussian + linear time trend. This can obvious be done with two different engines, but from a code maintenance and practical point of view, this is not optimal. I can pass a flag "fit linear trend" and use it to omit the linear trend component, but this then creates problems with the calculation of my Hessian and the sds ie the matrix ends up being singular, because some of the parameters are not used....
