16 /* The purpose of this file is to handle the case where we're
17 installing from files that already exist in the current directory.
18 If a setup.ini file is present, we set the mirror site to "." and
19 pretend we're installing from the `internet' ;-) else we have to
20 find all the .tar.gz files, deduce their versions, and try to
21 compare versions in the case where the current directory contains
22 multiple versions of any given package. We do *not* try to compare
23 versions with already installed packages; we always choose a
24 package in the current directory over one that's already installed
25 (otherwise, why would you have asked to install it?). Note
26 that we search recursively. */
