Item5895: I need to enumerate 'optional' DEPENDANCIES

for example, JSPopup can work without dojo / yui, but workd much better with one of those 2 installed.

so i want something like

( YuiContrib,>0,perl | DojoContrib,>0,perl), Optional

Tricky. But do-able. Definitely an enhancement.

Confirmed.

Looks like a duplicate of Item862, but as this one is more precise, I'll discard the other one.

It appears as though this is actually implemented. The Extension installer skips any dependency with the description beginning with the word Optional. I duplicated the functionality in Trunk rewrite of the extension installer, though the feature appeared to be already in the code. This is documented in the Trunk version of the BuildContrib extension. This can probably be closed.
