+Welcome to serf, a high-performance asynchronous HTTP client library.
+
+The serf library is a C-based HTTP client library built upon the Apache
+Portable Runtime (APR) library. It multiplexes connections, running the
+read/write communication asynchronously. Memory copies and transformations are
+kept to a minimum to provide high performance operation.
+
+ * Status: http://code.google.com/p/serf/wiki/
+ * Site: http://code.google.com/p/serf/
+ * Code: http://serf.googlecode.com/svn/
+ * Issues: http://code.google.com/p/serf/issues/list
+ * Mail: serf-dev@googlegroups.com
+ * People: Justin Erenkrantz, Greg Stein
+
+----
+
+Quick guide for the impatient
+
+ (Unix)
+ % ./configure
+ % make
+ % make install
+
+----
+
+Building serf from a Subversion checkout (non-packaged releases)
+
+We suggest that you try out 'serfmake'.
+
+ % ./serfmake --prefix=/usr/local/serf --with-apr=/usr/local/apr install
+
+If you want to use the autoconf build system and are using a Subversion
+checkout, you need to run buildconf and have APR and APR-util sources handy.
+
+ % ./buildconf --with-apr=/path/to/apr --with-apr-util=/path/to/apr-util
+ (By default, buildconf will look in . and ../ for apr and apr-util.)
+
+Then, you can use ./configure, make, etc.

+dnl find_apr.m4 : locate the APR include files and libraries
+dnl
+dnl This macro file can be used by applications to find and use the APR
+dnl library. It provides a standardized mechanism for using APR. It supports
+dnl embedding APR into the application source, or locating an installed
+dnl copy of APR.
+dnl
+dnl APR_FIND_APR(srcdir, builddir, implicit-install-check, acceptable-majors,
+dnl detailed-check)
+dnl
+dnl where srcdir is the location of the bundled APR source directory, or
+dnl empty if source is not bundled.
+dnl
+dnl where builddir is the location where the bundled APR will will be built,
+dnl or empty if the build will occur in the srcdir.
+dnl
+dnl where implicit-install-check set to 1 indicates if there is no
+dnl --with-apr option specified, we will look for installed copies.
+dnl
+dnl where acceptable-majors is a space separated list of acceptable major
+dnl version numbers. Often only a single major version will be acceptable.
+dnl If multiple versions are specified, and --with-apr=PREFIX or the
+dnl implicit installed search are used, then the first (leftmost) version
+dnl in the list that is found will be used. Currently defaults to [0 1].
+dnl
+dnl where detailed-check is an M4 macro which sets the apr_acceptable to
+dnl either "yes" or "no". The macro will be invoked for each installed
+dnl copy of APR found, with the apr_config variable set appropriately.
+dnl Only installed copies of APR which are considered acceptable by
+dnl this macro will be considered found. If no installed copies are
+dnl considered acceptable by this macro, apr_found will be set to either
+dnl either "no" or "reconfig".
+dnl
+dnl Sets the following variables on exit:

+dnl apr_found : "yes", "no", "reconfig"
+dnl
+dnl apr_config : If the apr-config tool exists, this refers to it. If
+dnl apr_found is "reconfig", then the bundled directory
+dnl should be reconfigured *before* using apr_config.
+dnl
+dnl Note: this macro file assumes that apr-config has been installed; it
+dnl is normally considered a required part of an APR installation.
+dnl
+dnl If a bundled source directory is available and needs to be (re)configured,
+dnl then apr_found is set to "reconfig". The caller should reconfigure the
+dnl (passed-in) source directory, placing the result in the build directory,
+dnl as appropriate.
+dnl
+dnl If apr_found is "yes" or "reconfig", then the caller should use the
+dnl value of apr_config to fetch any necessary build/link information.

+dnl
+dnl where implicit-install-check set to 1 indicates if there is no
+dnl --with-apr-util option specified, we will look for installed copies.
+dnl
+dnl where acceptable-majors is a space separated list of acceptable major
+dnl version numbers. Often only a single major version will be acceptable.
+dnl If multiple versions are specified, and --with-apr-util=PREFIX or the
+dnl implicit installed search are used, then the first (leftmost) version
+dnl in the list that is found will be used. Currently defaults to [0 1].
+dnl
+dnl where detailed-check is an M4 macro which sets the apu_acceptable to
+dnl either "yes" or "no". The macro will be invoked for each installed
+dnl copy of APU found, with the apu_config variable set appropriately.
+dnl Only installed copies of APU which are considered acceptable by
+dnl this macro will be considered found. If no installed copies are
+dnl considered acceptable by this macro, apu_found will be set to either
+dnl either "no" or "reconfig".
+dnl
+dnl Sets the following variables on exit:
+dnl
+dnl apu_found : "yes", "no", "reconfig"
+dnl
+dnl apu_config : If the apu-config tool exists, this refers to it. If
+dnl apu_found is "reconfig", then the bundled directory
+dnl should be reconfigured *before* using apu_config.
+dnl
+dnl Note: this macro file assumes that apr-config has been installed; it
+dnl is normally considered a required part of an APR installation.
+dnl
+dnl Note: At this time, we cannot find *both* a source dir and a build dir.
+dnl If both are available, the build directory should be passed to
+dnl the --with-apr-util switch.
+dnl
+dnl Note: the installation layout is presumed to follow the standard
+dnl PREFIX/lib and PREFIX/include pattern. If the APU config file
+dnl is available (and can be found), then non-standard layouts are
+dnl possible, since it will be described in the config file.
+dnl
+dnl If a bundled source directory is available and needs to be (re)configured,
+dnl then apu_found is set to "reconfig". The caller should reconfigure the
+dnl (passed-in) source directory, placing the result in the build directory,
+dnl as appropriate.
+dnl
+dnl If apu_found is "yes" or "reconfig", then the caller should use the
+dnl value of apu_config to fetch any necessary build/link information.

+TOPICS
+
+ 1. Introduction
+ 2. Thread Safety
+ 3. Pool Usage
+ 4. Bucket Read Functions
+ 5. Versioning
+ 6. Bucket lifetimes
+
+
+-----------------------------------------------------------------------------
+
+1. INTRODUCTION
+
+This document details various design choices for the serf library. It
+is intended to be a guide for serf developers. Of course, these design
+principles, choices made, etc are a good source of information for
+users of the serf library, too.
+
+
+-----------------------------------------------------------------------------
+
+2. THREAD SAFETY
+
+The serf library should contain no mutable globals, making it is safe
+to use in a multi-threaded environment.
+
+Each "object" within the system does not need to be used from multiple
+threads at a time. Thus, they require no internal mutexes, and can
+disable mutexes within APR objects where applicable (e.g. pools that
+are created).
+
+The objects should not have any thread affinity (i.e. don't use
+thread-local storage). This enables an application to use external
+mutexes to guard entry to the serf objects, which then allows the
+objects to be used from multiple threads.
+
+
+-----------------------------------------------------------------------------
+
+3. POOL USAGE
+
+For general information on the proper use of pools, please see:
+
+ http://cvs.apache.org/viewcvs/*checkout*/apr/docs/pool-design.html
+
+Within serf itself, the buckets introduce a significant issue related
+to pools. Since it is very possible to end up creating *many* buckets
+within a transaction, and that creation could be proportional to an
+incoming or outgoing data stream, a lot of care must be take to avoid
+tying bucket allocations to pools. If a bucket allocated any internal
+memory against a pool, and if that bucket is created an unbounded
+number of times, then the pool memory could be exhausted.
+
+Thus, buckets are allocated using a custom allocator which allows the
+memory to be freed when that bucket is no longer needed. This
+contrasts with pools where the "free" operation occurs over a large
+set of objects, which is problematic if some are still in use.
+
+### need more explanation of strategy/solution ...
+
+
+-----------------------------------------------------------------------------
+
+4. BUCKET READ FUNCTIONS
+
+The bucket reading and peek functions must not block. Each read
+function should return (up to) the specified amount of data. If
+SERF_READ_ALL_AVAIL is passed, then the function should provide
+whatever is immediately available, without blocking.
+
+The peek function does not take a requested length because it is
+non-destructive. It is not possible to "read past" any barrier with a
+peek function. Thus, peek should operate like SERF_READ_ALL_AVAIL.
+
+The return values from the read functions should follow this general
+pattern:
+
+ APR_SUCCESS Some data was returned, and the caller can
+ immediately call the read function again to read
+ more data.
+
+ NOTE: when bucket behavior tracking is enabled,
+ then you must read more data from this bucket
+ before returning to the serf context loop. If a
+ bucket is not completely drained first, then it is
+ possible to deadlock (the server might not read
+ anything until you read everything it has already
+ given to you).
+
+ APR_EAGAIN Some data was returned, but no more is available
+ for now. The caller must "wait for a bit" or wait
+ for some event before attempting to read again
+ (basically, this simply means re-run the serf
+ context loop). Though it shouldn't be done, reading
+ again will, in all likelihood, return zero length
+ data and APR_EAGAIN again.
+
+ NOTE: when bucket behavior tracking is enabled,
+ then it is illegal to immediately read a bucket
+ again after it has returned APR_EAGAIN. You must
+ run the serf context loop again to (potentially)
+ fetch more data for the bucket.
+
+ APR_EOF Some data was returned, and this bucket has no more
+ data available and should not be read again. If you
+ happen to read it again, then it will return zero
+ length data and APR_EOF.
+
+ NOTE: when bucket behavior tracking is enabled,
+ then it is illegal to read this bucket ever again.
+
+ other An error has occurred. No data was returned. The
+ returned length is undefined.
+
+In the above paragraphs, when it says "some data was returned", note
+that this could be data of length zero.
+
+If a length of zero is returned, then the caller should not attempt to
+dereference the data pointer. It may be invalid. Note that there is no
+reason to dereference that pointer, since it doesn't point to any
+valid data.
+
+Any data returned by the bucket should live as long as the bucket, or
+until the next read or peek occurs.
+
+The read_bucket function falls into a very different pattern. See its
+doc string for more information.
+
+
+-----------------------------------------------------------------------------
+
+5. VERSIONING
+
+The serf project uses the APR versioning guidelines described here:
+
+ http://apr.apache.org/versioning.html
+
+
+-----------------------------------------------------------------------------
+
+6. BUCKET LIFETIMES
+
+### flesh out. basically: if you hold a bucket pointer, then you own
+### it. passing a bucket into another transfers ownership. use barrier
+### buckets to limit destruction of a tree of buckets.
+
+
