-This tool was designed to mimic debian's uscan, but there is a major difference between the two: uscan uses a specific "watch" file that describe how it should scan packages, while euscan uses only what can already be found in ebuilds. Of course, we could later add some informations in metadata.xml to help euscan do its job more efficiently.

 For example for app-accessibility/dash-4.10.1, SRC_URI is:
   mirror://gnome/sources/dasher/4.10/dasher-4.10.1.tar.bz2
 euscan will scan pages based on this template:
   http://ftp.gnome.org/pub/gnome/sources/dasher/${0}.${1}/dasher-${PV}.tar.bz2
 
-Then, from that, it will scan the top-most directory that doesn't depend on the version, and try to go deeper from here.

-Disable brute force on those packages and urls. Most of the time it's because upstream is broken and will answer HTTP 200 even if the file doesn't exist.
