+This directory contains files used in gecko builds from libav
+(http://libav.org). The current files are from v11.3 of the library.
+All source files match their path from the library's source archive.
+
+Currently, we only use the fft portion of the library, and only on x86
+based platforms. If this changes, configuration files will most likely
+need to be updated.
+
+Configuration files were initially generated by running configure on
+the libav project, then dividing the config.h files into multiple
+files to reduce repeated entries. config_common.h contains package and
+architecture configuration information, and are used on all platforms.
+Platform specific config files (config_win.h/asm, config_unix.h/asm,
+etc) contain platform specific header information. .asm files should
+match their .h counterparts.
+
+If new architectures or projects are added, we will need to update
+defines to the config_common files. Platform headers should only need
+to be changed if we upgrade libav versions and require new headers to
+be found. \ No newline at end of file
