+Installation Instructions
+=========================
+
+Basic Installation
+------------------
+
+Building this software requires only Python. To install with default options:
+
+ ./waf configure
+ ./waf
+ ./waf install
+
+You may need to become root for the install stage, for example:
+
+ sudo ./waf install
+
+Configuration Options
+---------------------
+
+All supported options can be viewed using the command:
+
+ ./waf --help
+
+Most options only need to be passed during the configure stage, for example:
+
+ ./waf configure --prefix=/usr
+ ./waf
+ ./waf install
+
+Compiler Configuration
+----------------------
+
+Several standard environment variables can be used to control how compilers are
+invoked:
+
+ * CC: Path to C compiler
+ * CFLAGS: C compiler options
+ * CXX: Path to C++ compiler
+ * CXXFLAGS: C++ compiler options
+ * CPPFLAGS: C preprocessor options
+ * LINKFLAGS: Linker options
+
+Installation Directories
+------------------------
+
+The --prefix option (or the PREFIX environment variable) can be used to change
+the prefix which all files are installed under. There are also several options
+allowing for more fine-tuned control, see the --help output for details.
+
+Packaging
+---------
+
+Everything can be installed to a specific root directory by passing a --destdir
+option to the install stage (or setting the DESTDIR environment variable),
+which adds a prefix to all install paths. For example:
+
+ ./waf configure --prefix=/usr
+ ./waf
+ ./waf install --destdir=/tmp/package

-Autowaf
-=======
+Jalv
+====
-This is autowaf, a bundle of waf and a few extensions intended to be easy to
-use directly as source code in a project. Using this as a submodule or subtree
-named `waflib` in a project allows waf to be used without including binary
-encoded data in the waf script. This gets along with revision control and
-distributions better, among other advantages, without losing
-self-containedness.
+Jalv is a simple but fully featured LV2 host for Jack which exposes plugin
+ports to Jack, essentially making any LV2 plugin function as a Jack
+application.
+For more information, see <http://drobilla.net/software/jalv>.
-To use this in a project, add this repository as a directory named `waflib` in
-the top level of the project, and link or copy `waf` to the top level.
+Jalv is a small program which is useful, but also intended to be an appropriate
+test host for plugin development. It runs plugins from the command line with
+no user interaction, is light enough to run in valgrind, and is capable of
+dumping all communication between the plugin and its UI in a human readable
+format.
-Two waf extras are also included: `autowaf.py` and `lv2.py`.
-
-The `autowaf.py` module is a kitchen sink of Python utilities for building
-consistent packages, and can be imported in a wcript as
-`waflib.extras.autowaf`.
-
-The `lv2.py` extra defines options for LV2 plugin installation paths. It can
-be used by calling `opt.load('lv2')` and `conf.load('lv2')` in the appropriate
-locations in a wscript.
+To make it simple to test plugins in hosts that use different toolkits, there
+are several Jalv executables: jalv, jalv.gtk, jalv.gtk3, jalv.gtkmm, jalv.qt4,
+and jalv.qt5.

+ @file symap.c Implementation of Symap, a basic symbol map (string interner).
+
+ This implementation is primitive, but has some desirable qualities: good
+ (O(lg(n)) lookup performance for already-mapped symbols, minimal space
+ overhead, extremely fast (O(1)) reverse mapping (ID to string), simple code,
+ no dependencies.
+
+ The tradeoff is that mapping new symbols may be quite slow. In other words,
+ this implementation is ideal for use cases with a relatively limited set of
+ symbols, or where most symbols are mapped early. It will not fare so well
+ with very dynamic sets of symbols. For that, you're better off with a
+ tree-based implementation (and the associated space cost, especially if you
+ need reverse mapping).

+Autowaf
+=======
+
+This is autowaf, a bundle of waf and a few extensions intended to be easy to
+use directly as source code in a project. Using this as a submodule or subtree
+named `waflib` in a project allows waf to be used without including binary
+encoded data in the waf script. This gets along with revision control and
+distributions better, among other advantages, without losing
+self-containedness.
+
+To use this in a project, add this repository as a directory named `waflib` in
+the top level of the project, and link or copy `waf` to the top level.
+
+Two waf extras are also included: `autowaf.py` and `lv2.py`.
+
+The `autowaf.py` module is a kitchen sink of Python utilities for building
+consistent packages, and can be imported in a wcript as
+`waflib.extras.autowaf`.
+
+The `lv2.py` extra defines options for LV2 plugin installation paths. It can
+be used by calling `opt.load('lv2')` and `conf.load('lv2')` in the appropriate
+locations in a wscript.
