=head1 NAME
ujconv -- reinvented iconv(1) using Unicode::Japanese
=head1 SYNOPSIS
ujconv [-f from_encoding] [-t to_encoding] [-s string] [files...]
ujconv -l
ujconv -h
ujconv -V
=head1 VERSION
ujconv 0.02
=head1 DESCRIPTION
B<ujconv> is an iconv-like tool which is written in perl using
Unicode::Japanese.
B<ujconv> reads text from STDIN or files, convert them, and print them to
STDOUT.
Available options are as follows. Each options can be in short form (-f) or long
form (--from):
=over 4
=item -f,--from I<from_encoding>
Convert characters from I<from_encoding>. Unlike B<iconv> this option can be
omitted. In that case, the encoding of the input is guessed by B<ujconv>.
=item -t,--to I<to_encoding>
Convert characters to I<to_encoding>.
=item -s,--string I<string>
Input from the argument string instead of file or STDIN.
=item -l,--list
List all available encodings, one name per each lines.
=item -h,--help
Print a short help message.
=item -V,--version
Print the version of B<ujconv>.
