===Unison With Scrivener===
 +
 
 +
Scrivener stores its projects as bundles (i.e. folders). Because Unison does not sync modification times of folders, changes to Scrivener projects do not get properly propagated. To get around this, I use this more complicated AppleScript to zip up any Scrivener projects -- the zipped file gets propagated properly, with the Scrivener project modification times properly preserved and transmitted. Needless to say, this is a hack; but I really want to sync my Scrivener projects on multiple machines!
