 # Queries the ABS
 # License: GPL3
 
-# TODO
+## TODO
 # * Add license text
-# * Use libremessages
+# * Add everything
+# * Compare pacman sync against ABS (db-functions could be useful)
+# * Create symlinks from pkgbase to pkgname[@] for easy package finding
+
+## GOALS
+# * Have a searchable database of PKGBUILD metadata
+# * Have an interface for source-only builds
+# * Possibility to hook up ABS dirs besides ABSROOT
+# * Tell updates and non available binary packages
