 ----
 A very simple AUR/ABS helper. Doesn't build packages, only gets the sources.

         -s        Search for <package>.
           -S        Search only in the sync db. Implies -s.
           -A        Search only in AUR. Implies -s.
-	        -d        Get the package sources (default).
-		      -D      Get the dependencies also. Implies -d.
+        -d        Get the package sources (default). Set twice to also get the dependencies.
+          -f        Force downloading package sources even if they are already present in the working directory.
+        -w <dir>  Set the working directory.
 
 You can override any value in the script in \$HOME/.config/zpac.rc.sh
 By default zpac downloads the sources into the current directory. Controlled by `$cfg_workdir`.
