+Memory sizes in htop are displayed as they are in tools from the GNU Coreutils
+(when ran with the --human-readable option). This means that sizes are printed
+in powers of 1024. (e.g., 1023M = 1072693248 Bytes)
+.LP
+The decision to use this convention was made in order to conserve screen space
+and make memory size representations consistent throughout htop.
