SALSA-Lib is a small, light-weight, hot and spicy version of
the ALSA library, mainly for embedded systems with limited
resources. The library is designed to be source-level
compatible with ALSA library API for limited contents. Most
of function calls are inlined, and accesses directly to the
hardware via system calls.
Some components like ALSA sequencer aren't supported, and
most of all, the alsa-lib plugins and configurations are
completely dropped. Thus, neither dmix nor format
conversion is available with SALSA-lib.

prompt "Build static library only"

help
This will build the static library only. On architectures with
a low register count (like ia32) this makes sense, due to
allowing the compiler to use one additional register and
speeding up things (if only one application uses this library)
Note: This feature does not work yet. For example the esound
daemon fails to link due to missing exported functions.
