=head1 NAME

encguess - guess character encodings of files

=head1 VERSION

$Id: encguess,v 0.2 2016/08/04 03:15:58 dankogai Exp $

=head1 SYNOPSIS

  encguess [switches] filename...

=head2 SWITCHES

=over 2

=item -h

show this message and exit.

=item -s

specify a list of "suspect encoding types" to test, 
seperated by either C<:> or C<,>

=item -S

output a list of all acceptable encoding types that can be used with
the -s param

=item -u

suppress display of unidentified types

=back

=head2 EXAMPLES:

=over 2

=item *

Guess encoding of a file named C<test.txt>, using only the default
suspect types.

   encguess test.txt

=item *

Guess the encoding type of a file named C<test.txt>, using the suspect
types C<euc-jp,shiftjis,7bit-jis>.

   encguess -s euc-jp,shiftjis,7bit-jis test.txt
   encguess -s euc-jp:shiftjis:7bit-jis test.txt

=item *

Guess the encoding type of several files, do not display results for
unidentified files.

   encguess -us euc-jp,shiftjis,7bit-jis test*.txt

=back

=head1 DESCRIPTION

The encoding identification is done by checking one encoding type at a
time until all but the right type are eliminated. The set of encoding
types to try is defined by the -s parameter and defaults to ascii,
utf8 and UTF-16/32 with BOM. This can be overridden by passing one or
more encoding types via the -s parameter. If you need to pass in
multiple suspect encoding types, use a quoted string with the a space
separating each value.
