.SH SYNOPSIS
.B renu
.RB [FILE]
.SH DESCRIPTION
Create a recursive menu described in FILE.
.PP
The FILE should have a specific format, each line representing an option.
.SS Menu (m name)
This line represents the start of a menu.
All the lines that follow, until another menu line is found, represent the entries of this menu.
The default name the program will open is 'def'.
.SS Empty line
.SS Comment (# ...)
If the line starts with a # or is empty, it is ignored and regarded as a comment.
.SS Submenu (s entry name)
The submenu line will open the menu with the specified name, once selected.
Entry is the displayed name.
The line takes two arguments.
.SS Print (p entry [value])
This option will print the value once selected.
The value is an optional argument and, if empty, entry will be printed.
.SS Run (r entry command)
This line takes two arguments.
The option will run the command as if it were run with sh -c "command".
.SS Arguments
Each line uses one or more arguments.
The arguments are separated by spaces, thus if you want to have spaces
in the arguments, you should either escape the space or use double quotes.
You can escape a character using backslash ('\\').
Note that the double quotes ('"') and backslashes ('\\') inside the argument always have to be escaped.
