+// Handle QWK packet transfers (uploads of REP packets and downloads of QWK packets)
 // in the Synchronet Web Server (e.g. using exec/qnet-http.js)
 
+// Although this script is really intended to be used with qnet-http.js, it
+// can be used with other http-clients (e.g. for use with other BBS software).
+// For example, using GNU Wget (place https:// before <hostname> for HTTPS):
+
+// Upload a REP packet:
+// $ wget --auth-no-challenge --post-file=<hub-ID>.qwk --http-user=<username>
+//        --http-password=<password> <hub-hostname>/qwk.ssjs
+       
+// Generate/download a QWK packet:
+// $ wget --auth-no-challenge --http-user=<username> --http-password=<password>
+//        --content-disposition <hub-hostname>/qwk.ssjs
+       
+// Confirm successful download of a QWK packet:
+// $ wget --auth-no-challenge --http-user=<username> --http-password=<password>
+//        --post-data= <hub-hostname>/qwk.ssjs?received=<QWK-file-length>
