The
documentation on ttree is incredibly sparse. (For example, there are no examples of actually doing something useful with ttree, only how to set options and configure the app.)
I never understood where it gets the actual content that will be fed into the templates. If you had a collection of text files for your content, how would you feed them to ttree? The docs just say ttree will "process ... template files," as though that is somehow useful in and of itself (??). Template files without corresponding content files don't seem very interesting to me.
I just never bothered messing with ttree. Easier to write my own perl scripts and use Template; than to figure out what this script (which I'm sure is useful to those in the know) is supposed to be doing.
Update: To avoid sounding too much like an ungrateful twit, I should note the Template Toolkit generally ROCKS, and I appreciate the time Andy put into it.
