On windows where no SVN_EDITOR is set often, 3-svn-remove.sh will fail

[CloCkWeRX]

Either this one should check for SVN_EDITOR, VISUAL or EDITOR, or it should be able to continue if the original repo has been removed and this is a second execution

Committed revision 319023.

When you hit ENTER, an editor will open svn:externals for packages-all.
Please delete the line referring to Image_Puzzle.
Then save and close the editor.

Hmm... -m "super cool message"?

Till: the externals file itself is being edited.

At "work", we have a script to update vendor libs and modules which we include using svn:externals. We scripted it up and do something like this:

$current = `exec svn propget svn:externals $path`;
// parse current >> $new
file_put_contents('./file', $new);
`exec svn propset svn:externals $path -F file`
unlink('./file');
`svn ci -m 'externals updated, blah blub' $path

(In a nutshell, pseudo-code.)

I'd probably make sure the $path is clean so you don't happen to commit other things.

Good idea Till. Script now manipulates the svn:externals locally.
