.SH DESCRIPTION
pyenigma.py is a command line for processing Enigma messages.
Enigma settings can either be specified by command-line arguments,
or read from a key file. If reading from a key file, the line labeled
with the current day number is used unless the \fB--day\fP argument is provided.
.PP
Text to process can be supplied 3 ways:
.RS
.IP \(bu 3
if \fB--text\fP=\fITEXT\fP is present \fITEXT\fP is processed
.IP \(bu 3
if \fB--file\fP=\fIFILE\fP is present the contents of \fIFILE\fP are processed
.IP \(bu 3
otherwise the text is read from standard input
.RE
.PP
Please see documentation for the description of the file format.

.SH EXAMPLE
Try these commands to specify settings from the command line:
.PP
.nf
.fam C
$ pyenigma.py \-r III IV V \-i 1 2 3 \-p AB CD EF GH IJ KL MN \-u B \-s XYZ
$ pyenigma.py \-r Beta III IV V \-i A B C D \-p 1/2 3/4 5/6 \-u B\-Thin \-s WXYZ
.fam T
.fi
This command will load Enigma settings from a file:
.PP
.nf
.fam C
$ pyenigma.py \-\-key-file=enigma.keys \-s XYZ \-t HELLOXWORLDX
.fam T
