KDevelop ctags symbol browsing on external dependencies (solution)

[Roland Krause]

Markus,
I looked at your patch and while the idea is very good, I am not sure
that this is really what we want. It'd be much better to implement a
dialog that allows the configuration of the ctags command and to have
multiple tags files. One for the actual project and another one for
source code that doesnt change as much, e.g. kdelibs, qt, /usr/include.
This tags file doesnt have to be regenerated and should be stored in a
central location.

Still, if you think it makes your live easier I can apply the patch.
There are definitely portability issues with the grep command,
especially on older Solaris.
