.SH DESCRIPTION
\fBerrno\fR looks up errno macro names,
errno codes, and the corresponding descriptions. For example,
if given \*(T<ENOENT\*(T> on a Linux system, it
prints out the code 2 and the description "No such file or directory".
If given the code 2, it prints \*(T<ENOENT\*(T>
and the same description.
.SH OPTIONS
.TP 
\*(T<\fB\-l\fR\*(T>, \*(T<\fB\-\-list\fR\*(T>
List all errno values.
.TP 
\*(T<\fB\-s\fR\*(T>, \*(T<\fB\-\-search\fR\*(T>
Search for errors whose description contains
all the given words (case-insensitive).
.TP 
\*(T<\fB\-S\fR\*(T>, \*(T<\fB\-\-search\-all\-locales\fR\*(T>
Like \*(T<\fB\-\-search\fR\*(T>, but searches all
installed locales.
