+Examples:
+    # Generate 2 threads each with 10 SMSes and 10 MMSes on device with phone
+    # number +16508619525. MMS messages use images listed in ./images, which list
+    # *.jpg and *.gif files in local directory. The SQL commands are in sql.txt
+    fillsms +16508619525 2 10 10 images sql.txt
+
+    # Same as above but only creating the SQL command file without pushing to
+    # device
+    fillsms -f +16508619525 2 10 10 images sql.txt
+
