+relies on several assumptions like having the block device write the correct
+sectors, etc.  For files it also doesn't work on log-structured file systems
+such as F2FS, JFFS, LogFS, etc.  You should @emph{not} trust @command{wipe} to
+work as advertised until you have manually verified that all its assumption
+hold true on your system.  To overwrite data it uses the Mersenne Twister
+pseudo-random number generator (PRNG) that is seeded with @file{/dev/urandom}
+or, if unavailable, @file{/dev/random}.")
