proj/gentoo: Initial commit
This commit represents a new era for Gentoo: Storing the gentoo-x86 tree in Git, as converted from CVS. This commit is the start of the NEW history. Any historical data is intended to be grafted onto this point. Creation process: 1. Take final CVS checkout snapshot 2. Remove ALL ChangeLog* files 3. Transform all Manifests to thin 4. Remove empty Manifests 5. Convert all stale $Header$/$Id$ CVS keywords to non-expanded Git $Id$ 5.1. Do not touch files with -kb/-ko keyword flags. Signed-off-by: Robin H. Johnson <robbat2@gentoo.org> X-Thanks: Alec Warner <antarus@gentoo.org> - did the GSoC 2006 migration tests X-Thanks: Robin H. Johnson <robbat2@gentoo.org> - infra guy, herding this project X-Thanks: Nguyen Thai Ngoc Duy <pclouds@gentoo.org> - Former Gentoo developer, wrote Git features for the migration X-Thanks: Brian Harring <ferringb@gentoo.org> - wrote much python to improve cvs2svn X-Thanks: Rich Freeman <rich0@gentoo.org> - validation scripts X-Thanks: Patrick Lauer <patrick@gentoo.org> - Gentoo dev, running new 2014 work in migration X-Thanks: Michał Górny <mgorny@gentoo.org> - scripts, QA, nagging X-Thanks: All of other Gentoo developers - many ideas and lots of paint on the bikeshed

+ <longdescription>
+ Typical buffer&amp;#x2013;based incremental I/O is based around a single loop,
+ which reads data from some source (such as a socket or file), transforms
+ it, and generates one or more outputs (such as a line count, HTTP
+ responses, or modified file). Although efficient and safe, these loops are
+ all single&amp;#x2013;purpose; it is difficult or impossible to compose
+ buffer&amp;#x2013;based processing loops.
+
+ Haskell&amp;#x2019;s concept of &amp;#x201C;lazy I/O&amp;#x201D; allows pure code to
+ operate on data from an external source. However, lazy I/O has several
+ shortcomings. Most notably, resources such as memory and file handles can
+ be retained for arbitrarily long periods of time, causing unpredictable
+ performance and error conditions.
+
+ Enumerators are an efficient, predictable, and safe alternative to lazy
+ I/O. Discovered by Oleg Kiselyov, they allow large datasets to be processed
+ in near&amp;#x2013;constant space by pure code. Although somewhat more complex
+ to write, using enumerators instead of lazy I/O produces more correct
+ programs.
+
+ This library contains an enumerator implementation for Haskell, designed to
+ be both simple and efficient. Three core types are defined, along with
+ numerous helper functions:
+
+ * /Iteratee/: Data sinks, analogous to left folds. Iteratees consume
+ a sequence of /input/ values, and generate a single /output/ value.
+ Many iteratees are designed to perform side effects (such as printing to
+ @stdout@), so they can also be used as monad transformers.
+
+ * /Enumerator/: Data sources, which generate input sequences. Typical
+ enumerators read from a file handle, socket, random number generator, or
+ other external stream. To operate, enumerators are passed an iteratee, and
+ provide that iteratee with input until either the iteratee has completed its
+ computation, or EOF.
+
+ * /Enumeratee/: Data transformers, which operate as both enumerators and
+ iteratees. Enumeratees read from an /outer/ enumerator, and provide the
+ transformed data to an /inner/ iteratee.
