* <misiek@misiek.eu.org>)
* Ported to Busybox - Alfred M. Szmidt <ams@trillian.itslinux.org>
* Removed --version/-V and --help/-h in
- * Removed prase_error(), using errorMsg() from Busybox instead
+ * Removed prase_error(), using error_msg() from Busybox instead
* Replaced our_malloc with xmalloc and our_realloc with xrealloc
