-# "Poem" - Lightweight POSIX Emulation
-
-Before Starboard, we had tried to build a POSIX emulation layer for every
-platform we wanted to support. This meant replacing link symbols in some cases,
-and a wielding global preprocessor macros in others. It was impossible to keep
-inclusion of platform headers (e.g. `winsock.h`) from transitively leaking out
-into common code.
-
-`poem`, for POsix EMulation, is somewhat similar, but a surgical tool for
-targeted porting, rather than a blunt instrument. Because we have Starboard as a
-well-defined barrier, we can use the preprocessor to selectively redirect
-standard functions like malloc to Starboard without making lots of changes to
-the code.
-
-The rule we use is that these headers must ONLY be included in implementation
-files, not headers, so that the preprocessor replacements don't spread
-uncontrollably.
-
-For each `poem`, we try to name files in a consistent, formulaic manner.  With
-this scheme, we can easily determine the correct poem header while porting.
-This can also come handy if one were to write a script to assist in porting
-third party libraries.  In theory, the script would just look for includes
-in .cc files, where we have available poems and then wrap unprotected includes
-in #if !defined(STARBOARD), and include the poems if STARBOARD is defined.
