building docs in correct order
Created by: nschloe
When building the documentation of only a few Trilinos packages, one can descend into package/<name>/doc/
and call ./build_docs
there. Unfortunately, this may lead to errors of the kind
error: Tag file `/«PKGBUILDDIR»/packages/amesos/doc/../../../packages/common/tag_files/teuchosBrowser.tag' does not exist or is not a file. Skipping it...
if the documentation of the dependent package hasn't been built yet.
