Hey Rich,  This information is outdated (I know you got it from me).  When you originally forked this was true and this method work for Tomcat 6, but not Tomcat 7 (this is what i was fixing when we were on chat that first day).  The geotiff-iosp jar from the original build  included all the required dependencies but, again, this wouldn't work with Tomcat 7.  THe build was modified to address this.  With the new build, the geotiff-isop jar doesn't contain any dependencies (there are a number of these).  So as the project currently stands the geotiff-iosp needs some additional jars.  *Now* this is why I've been draggin' my feet releasing this publicly.  The list of dependencies changes depending on how you are using the IOSP (NetCDF-Java, ToolsUI versus TDS) *and* what you have installed on your local machine *and* what OS you are running...  (it's related to the Java Image IO and Java Advanced Imaging libraries)

So...  This is why the project now contains a "thredds" subproject.  If you build the project from the root, it will build the geotiff-iosp and then also create a thredds.war (using a technique called "maven war overlay") with all the appropriate jars needed to run in the in thredds injected into the WEB-INF/lib of the newly created thredds.war.  This will work for all platforms, but may have issues with Mac OS X users running Java 1.6  *phew*.

I can accept the pull then update the docs, or you can make the edit and push them (they will be automatically appended to this pull request).
