 language.  The library is nascent, so it doesn't have enough to warrant a
 release. This is a library of header files, in the same spirit as [boost].
 
+Here are some of the features present in the library:
+
+- check macros (assertions that aren't meant to be removed in releases)
+- RAII utilities, such as for closing file descriptors
+- low-level system information from cpuid
+- file I/O utilities, such as reading complete files
+- hash functions
+- pseudo-random number generators
+- error handling, such as `die()`
+- function delegates (for use with C functions that take `(void*)(void*)`)
+- region-based allocation
+- bundles of header includes
+- socket utilities
+- C functions for string manipulation
+- bit manipulation
+- C++ support for pthreads, but allowing the user to access the underlying
+  `pthread_t` (a major annoyance of using boost threads was its complete
+  encapsulation)
+- portable re-implementations of pthread primitives such as barriers
+- C++ support for [State Threads]
+- utilities for [tamer]

 Code found here generally tries to complement code in the following other handy
 libraries:
 
-- [boost]
-- [libstdc++]
-- [nmstl]
+- [boost]: mountains of goodness
+- [libstdc++]: GNU's popular STL implementation
+- [stlport]: portable SGI-derived STL implementation that has the extensions
+  like `hash_map`
+- [State Threads]: lightweight cooperative threads library that focuses on
+  performance and provides network IO.

+This is a script for helping me publish, in the hopes of getting more into the
+whole "release early and often" mantra.  It takes care of the generation of the
+project website and publishing this to assorted.sf.net, and it also packages up
+and releases the software package.
+
+In both website generation and packaging, the process involves generation of a
+final README from the source README.  For releasing a package, the place to
+upload the files is determined by the package type (most things default to
+Google Code, but Python packages are pushed to PyPI, for instance).

 Aside from its simplicity, efficiency, and support for scheduled tasks, it also
 has no dependencies except for Java 6.  Currently only UDP is supported.
