library.  It tries to be memory efficient and reasonably fast.  It has
features such as:
@itemize
@item
Decoding support for any image that the PNG standard allows.  This includes all
standard color modes, all bit depths, all transparency, and interlacing and
filtering options.
@item
Encoding support for images of all color modes (true color, grayscale, and
indexed) and transparency for all these color modes.  The best color mode is
chosen automatically, based on the amount of used colors.
@item Read/write access to the image's pixels.
@item Read/write access to all image metadata that is stored in chunks.
@item
Memory efficiency: @code{fixnum} are used, i.e. 4 or 8 bytes of memory per
pixel, depending on the hardware).
@item
Performance: ChunkyPNG is reasonably fast for Ruby standards, by only using
integer math and a highly optimized saving routine.
@item Interoperability with RMagick.
@end itemize

ChunkyPNG is vulnerable to decompression bombs and can run out of memory when
loading a specifically crafted PNG file.  This is hard to fix in pure Ruby.
Deal with untrusted images in a separate process, e.g., by using @code{fork}
or a background processing library.")

improving coverage.

Integration with RSpec, Minitest, Travis & Coveralls - no need to configure
anything - out of the box support for these platforms.

It supports coverage of views -- templates compiled to Ruby code can be

     "Mail is an internet library for Ruby that is designed to handle email
generation, parsing and sending.  The purpose of this library is to provide
a single point of access to handle all email functions, including sending
and receiving emails.  All network type actions are done through proxy
methods to @code{Net::SMTP}, @code{Net::POP3} etc.

Mail has been designed with a very simple object oriented system that
really opens up the email messages you are parsing, if you know what you
are doing, you can fiddle with every last bit of your email directly.")

fact is that most parsers are insensitive to indentation.  If, however, the

indentation will probably be an issue and hence this gem.")
