PSP are expected to be its principle user group.

Features:
@enumerate
@item Generates HTML, SGML, XML, SQL, Postscript, form email, LaTeX, or any other
   text-based format.
@item Cleanly separates content, graphic design, and program code.
@item Blends the power and flexibility of Python with a simple template language
   that non-programmers can understand.
@item Gives template writers full access to any Python data structure, module,
   function, object, or method in their templates.
@item Makes code reuse easy by providing an object-orientated interface to
   templates that is accessible from Python code or other Cheetah templates.
   One template can subclass another and selectively reimplement sections of it.
@item Provides a simple, yet powerful, caching mechanism that can dramatically
   improve the performance of a dynamic website.
@item Compiles templates into optimized, yet readable, Python code.

PNG files with all allowable bit depths (1/2/4/8/16/24/32/48/64 bits per
pixel) and colour combinations: greyscale (1/2/4/8/16 bit); RGB, RGBA,
LA (greyscale with alpha) with 8/16 bits per channel; colour mapped
images (1/2/4/8 bit).  Adam7 interlacing is supported for reading and writing.
A number of optional chunks can be specified (when writing) and
understood (when reading): tRNS, bKGD, gAMA.

PyPNG is not a high level toolkit for image processing (like PIL) and does not
aim at being a replacement or competitor.  Its strength lies in fine-grained
extensive support of PNG features.  It can also read and write Netpbm PAM
files, with a focus on its use as an intermediate format for implementing
custom PNG processing.")
