.SH DESCRIPTION
.B eddie
evalutes the provided
.I expression
on either the contents of the
.I file
arguments concatenated together,
or standard input if no file arguments are present.
.PP
If the
.B \-l
option is used, the 
.I expression
is used to process each line instead of the entire contents.
.PP
The prelude, Data.List and Data.Char modules are available for building
expressions. Other modules may be added with the
.B \-M
and
.B \-m
options.
.SH OPTIONS
.IP \-e
The
.BI \-e\  expr
(long form
.BI \-\-expr\  expr)
option concatenates it's value to the
haskell expression being evaluated with a newline separator.
Multiple occurrences can be used to build up a
multi-line expression.
.IP ""
If no
.BI \-e\  expr
option is present, the first non-flag argument will be used for
the haskell expression.
.IP \-l
The
.B \-l
(long form
.B \-\-line
)
option causes
.B eddie
to process input line at a time. The
.I expr
will be run on each line and the results concatenated together.
.RS
.PP
The command
.RS
.PP
.B eddie \-l
.I expr file ...
.RE
.PP
is equivalent to the command
.RS
.PP
.B eddie
"unlines . map
.I expr
\&. lines"
.I file ...
.
.RE 1
.IP \-m
The
.BI \-m name
(long form
.BI \-\-module name
)
option is used to import module
.I name
into haskell before evaluating the expression.
.IP \-M
The
.BI \-M name,as
(long form
.BI \-\-Modules name,as
)
option imports the
.I name
module using a qualified import with an as clause,
