allows you to change how you run your code, not how you write it.
It uses @code{epoll} or @code{libevent} for highly scalable non-blocking I/O.
Coroutines ensure that the developer uses a blocking style of programming
that is similar to threading, but provide the benefits of non-blocking I/O.
The event dispatch is implicit, which means you can easily use @code{Eventlet}
from the Python interpreter, or as a small part of a larger application.")

used in @code{scipy.sparse}.  These differences make this project useful in
certain situations where @code{scipy.sparse} matrices are not well suited, but
it should not be considered a full replacement.  It lacks layouts that are not
easily generalized like @dfn{compressed sparse row/column}(CSR/CSC) and

     "Grandalf is a Python package made for experimentations with graphs
drawing algorithms.  It is written in pure Python, and currently implements
two layouts: the Sugiyama hierarchical layout and the force-driven or energy
minimization approach.  While not as fast or featured as graphviz or other
libraries like OGDF (C++), it provides a way to walk and draw graphs no larger
than thousands of nodes, while keeping the source code simple enough to tweak
and hack any part of it for experimental purpose.  With a total of about 1500
lines of Python, the code involved in drawing the Sugiyama (dot) layout fits
in less than 600 lines.  The energy minimization approach is comprised of only
250 lines!

Grandalf does only 2 not-so-simple things:
@itemize
@item computing the nodes (x,y) coordinates (based on provided nodes
dimensions, and a chosen layout)
@item routing the edges with lines or nurbs
@end itemize

It doesn’t depend on any GTK/Qt/whatever graphics toolkit.  This means that it
will help you find where to draw things like nodes and edges, but it’s up to
you to actually draw things with your favorite toolkit.")

type hinting stub files, especially interesting for linting typeshed.  It
adds the @file{.pyi} extension to the default value of the @code{--filename}
command-line argument to Flake8.  This means stubs are linted by default with
this plugin enabled, without needing to explicitly list every file.  It
modifies PyFlakes runs for @file{.pyi} files to defer checking type annotation
expressions after the entire file has been read.  This enables support for
first-class forward references that stub files use.")

     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

     It provides a compatible representation which comes from the _ast module.  It
     rebuilds the tree generated by the builtin _ast module by recursively walking
     down the AST and building an extended ast.  The new node classes have
     additional methods and attributes for different usages.  They include some
     support for static inference and local name scopes.  Furthermore, astroid
     builds partial trees by inspecting living objects.")

     "@acronym{arcp, Archive and Package} provides functions for creating
     @code{arcp_} URIs, which can be used for identifying or parsing hypermedia files
     packaged in an archive or package, like a ZIP file.  arcp URIs can be used to
     consume or reference hypermedia resources bundled inside a file archive or an
     application package, as well as to resolve URIs for archive resources within a
     programmatic framework.  This URI scheme provides mechanisms to generate a
     unique base URI to represent the root of the archive, so that relative URI
     references in a bundled resource can be resolved within the archive without
     having to extract the archive content on the local file system.  An arcp URI can
     be used for purposes of isolation (e.g. when consuming multiple archives),
     security constraints (avoiding \"climb out\" from the archive), or for
     externally identiyfing sub-resources referenced by hypermedia formats.")

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.")

supports x86_64 instructions up to AVX-512 and SHA.")
