Recover from wstool init failure
I'm following the Installation/Source and ran the following command:
wstool init -j8 src hydro-desktop-wet.rosinstall
turtlesim failed to downloads so I stopped the command when running it again:
wstool init -j8 src hydro-desktop-full-wet.rosinstall
I get the following:
Error: There already is a workspace config file .rosinstall at "src". Use wstool install/modify.
How do I proceed? I want to be able to run the command again, have it download what's missing (hopefully just turtlesim) and continue on. This should be documented on the wiki.
