+## TODO
+# * Add license text
+# * Create symlinks from pkgbase to pkgname[@] for easy package finding
+# * Use lastsync to store processed packages
+
+## GOALS
+# * Have a searchable database of PKGBUILD metadata
+# * Have an interface for source-only builds
+# * Possibility to hook up ABS dirs besides ABSROOT (low priority)
+# * Tell updates and non available binary packages (working on this)
