+This is the Portable Linux Processor Affinity (PLPA) package
+(pronounced "pli-pa").  It is intended for developers who wish to use
+Linux processor affinity via the sched_setaffinity() and
+sched_getaffinity() library calls, but don't want to wade through the
+morass of 3 different APIs that have been offered through the life of
+these calls in various Linux distributions and glibc versions.

+ * Some notes about the declarations and definitions in this file:
+ *
+ * This file is a mix of internal and public declarations.
+ * Applications are warned against using the internal types; they are
+ * subject to change with no warning.
+ *
+ * The PLPA_NAME() and PLPA_NAME_CAPS() macros are used for prefixing
+ * the PLPA type names, enum names, and symbol names when embedding
+ * PLPA.  When not embedding, the default prefix is "plpa_" (or
+ * "PLPA_" when using PLPA_NAME_CAPS()).  Hence, if you see a
+ * declaration like this:
+ *
+ * int PLPA_NAME(foo)(void);
+ *
+ * It's a function named plpa_foo() that returns an int and takes no
+ * arguments when building PLPA as a standalone library.  It's a
+ * function with a different prefix than "plpa_" when the
+ * --enable-included-mode and --with-plpa-symbol-prefix options are
+ * supplied to PLPA's configure script.
