          featured    These modules have been nominated by the crew for either 
                      outstanding quality, technique or creativity 
                      (or combination of).

          new         Same than uploads but using search engine

          random      Ramdom module from entire archive

   -a <artist>  Search in artist database
   -m <module>  Search in module database (Title and Filename)
   -g <genre>   Download a specific genre (for the time being this must be done
		by using the genre number at modarchive.org. In order to get the
		number, go to modarchive.org and click the genres page. Hover your
		mouse over the genre and look for the number in the link address.)
		Genre will also ask you for a page number. This is refering to the
		search results page. Leave blank for page 1, then run the script 
		again and enter 2, 3, 4, etc... if you want to download the rest 
		of the pages.


Hint: Use + symbol instead blankspaces in search strings.
Hint 2: if you're running Mac OSX, you must first run this command before the script will run: function _wget() { curl "${1}" -o $(basename "${1}") ; };
