+check_memfree v1.0
+
+Check free memory space on local machine.
+
+Usage: 
+check_memfree [-hV] -w <percent_free>% -c <percent_free>%
+check_memfree [-hV] -w <bytes_free> -c <bytes_free>
+
+Options:
+ -h
+    Print detailed help screen
+ -V
+    Print version information
+ -w INTEGER
+    Exit with WARNING status if less than INTEGER bytes of memory space are free
+ -w PERCENT%
+    Exit with WARNING status if less than PERCENT of memory space is free
+ -c INTEGER
+    Exit with CRITICAL status if less than INTEGER bytes of memory space are free
+ -c PERCENT%
+    Exit with CRITCAL status if less than PERCENT of memory space is free
