From my cursory understanding (based solely on the README), it seems that `try`s are just directories, so that they can automatically be slung around, without any need for a backing database:

> Sometimes, you might want to pre-execute a command and commit its result at a later time. Invoking try with the -n flag will return the overlay directory, without committing the result.

Also:

> curl install tries

… my brain instantly translated that to "curly fries". Built-in auto-correct!
