+ functionality is currently limited to x86, ARM, and SH3/4.
+
+Supported libcs:
+
+ glibc-2.0.x, glibc-2.1.x, Linux-libc5, uClibc. People are looking at
+ newlib and diet-libc, but consider them unsupported, untested, or worse.
+

+
+ Full functionality requires Linux 2.0.x, 2.2.x, or 2.4.x. A large fraction
+ of the code should run on just about anything.
