[gdome]how to check for gdome

[rob <mailingLists pangolin org uk>]

hi,

I'm moments away from releaseing the first version of my domTreeEditor
thingy. I'm just trying to get it the autoconf automake et al. working
nicely. I've never had to deal with them before so I'm a bit lost. 

Mainly I'm not sure how I check for gdome (and libxml2 for that matter) and
how I use gdome-config.

If any one has examples that'd be great.

Thanks

rob
