From the man page:
The mimencode program simply converts a byte stream into (or out of) one of
the standard mail encoding formats defined by MIME, the proposed standard
for internet multimedia mail formats. Such an encoding is necessary
because binary data cannot be sent through the mail. The encodings under-
stood by mimencode are preferable to the use of the uuencode/uudecode pro-
grams, for use in mail, in several respects that were important to the
authors of MIME.
Mmencode is part of metamail, and can be installed as part of that package.
It is provided here as an independent package since some programs require
mmencode only and hence you can avoid having to install the entire metalmail
package when not required.
libb64 is a library of ANSI C routines for fast encoding/decoding of data
into and from a Base64-encoded format. C++ wrappers are included, as well
as the source code for standalone encoding and decoding executables.
Base64 uses a subset of displayable ASCII characters, and is therefore a
useful encoding for storing binary data in a text file, such as XML, or
sending binary data over text-only communication channels.
This library provides an iconv() implementation, for use on systems which
don't have one, or whose implementation cannot convert from/to Unicode.
It can convert from any of these encodings to any other, through Unicode
conversion. It has also some limited support for transliteration, i.e.
when a character cannot be represented in the target character set, it can
be approximated through one or several similarly looking characters.
libiconv is for you if your application needs to support multiple character
encodings, but that support lacks from your system.
See either README or website for the list of supported encodings.
LuaIconv is a Lua binding to iconv library.
LuaJSON is a JSON parser/creator for Lua.
Mpack and munpack are utilities for encoding and decoding
(respectively) binary files in MIME (Multipurpose Internet Mail
Extensions) format mail messages. For compatibility with older forms
of transferring binary files, the munpack program can also decode
messages in split-uuencoded format.
[ excerpt from developer's www site ]
Nomyso is a Perl program which converts assembly language source
files for MASM and TASM to NASM-compatible source files.
This is a standalone converter for the OpenOffice.org swriter (*.sxw,*.odt)
and scalc (*.sxc) formats.
It doesn't depend on Open Office or any other external tools or libraries.
There are three output modules:
* o3read displays a dump of the parse tree
* o3totxt creates plain text
* o3tohtml creates html code
Example: unzip -p document.odt content.xml | o3totxt
Base64 is a group of similar binary-to-text encoding schemes that
represent binary data in an ASCII string format by translating it
into a radix-64 representation. It is specified in RFC 4648.
This module converts hashes of binary octets into ASCII messages
suitable for transfer over 6-bit clean transport channels. The
encoded ASCII resembles PGP's armoured messages, but are in no
way compatible with PGP.
