-/* Overview: 
-
-   There is a large number of synthesis packages in use or development
-   on the Linux platform at this time. This API (`The Linux Audio
-   Developer's Simple Plugin API') attempts to give programmers the
-   ability to write simple `plugin' audio processors in C/C++ and link
-   them dynamically (`plug') into a range of these packages (`hosts').
-   It should be possible for any host and any plugin to communicate
-   completely through this interface.
-
-   This API is deliberately short and simple. To achieve compatibility
-   with a range of promising Linux sound synthesis packages it
-   attempts to find the `greatest common divisor' in their logical
-   behaviour. Having said this, certain limiting decisions are
-   implicit, notably the use of a fixed type (LADSPA_Data) for all
-   data transfer and absence of a parameterised `initialisation'
-   phase. See below for the LADSPA_Data typedef.
-
-   Plugins are expected to distinguish between control and audio
-   data. Plugins have `ports' that are inputs or outputs for audio or
-   control data and each plugin is `run' for a `block' corresponding
-   to a short time interval measured in samples. Audio data is
-   communicated using arrays of LADSPA_Data, allowing a block of audio
-   to be processed by the plugin in a single pass. Control data is
-   communicated using single LADSPA_Data values. Control data has a
-   single value at the start of a call to the `run()' or `run_adding()'
-   function, and may be considered to remain this value for its
-   duration. The plugin may assume that all its input and output ports
-   have been connected to the relevant data location (see the
-   `connect_port()' function below) before it is asked to run.
-
-   Plugins will reside in shared object files suitable for dynamic
-   linking by dlopen() and family. The file will provide a number of
-   `plugin types' that can be used to instantiate actual plugins
-   (sometimes known as `plugin instances') that can be connected
-   together to perform tasks.
-
-   This API contains very limited error-handling. */
-
-/*****************************************************************************/
-
-/* Fundamental data type passed in and out of plugin. This data type
-   is used to communicate audio samples and control values. It is
-   assumed that the plugin will work sensibly given any numeric input
-   value although it may have a preferred range (see hints below). 
-
-   For audio it is generally assumed that 1.0f is the `0dB' reference
-   amplitude and is a `normal' signal level. */

-   satisfy all of the following:
-
-   (1) The plugin must not use malloc(), free() or other heap memory
-   management within its run() or run_adding() functions. All new
-   memory used in run() must be managed via the stack. These
-   restrictions only apply to the run() function.
-
-   (2) The plugin will not attempt to make use of any library
-   functions with the exceptions of functions in the ANSI standard C
-   and C maths libraries, which the host is expected to provide.
-
-   (3) The plugin will not access files, devices, pipes, sockets, IPC
-   or any other mechanism that might result in process or thread
-   blocking.
-      
-   (4) The plugin will take an amount of time to execute a run() or
-   run_adding() call approximately of form (A+B*SampleCount) where A
-   and B depend on the machine and host in use. This amount of time
-   may not depend on input signals or plugin state. The host is left
-   the responsibility to perform timings to estimate upper bounds for
-   A and B. */

-
-/* Plugin Port Range Hints: 
-
-   The host may wish to provide a representation of data entering or

-   this more meaningful, the plugin should provide `hints' to the host
-   describing the usual values taken by the data.
-   
-   Note that these are only hints. The host may ignore them and the
-   plugin must not assume that data supplied to it is meaningful. If

-   to run without failure and, where possible, produce a sensible
-   output (e.g. a high-pass filter given a negative cutoff frequency
-   might switch to an all-pass mode).

-   proceed from there.

-   Plugin types are accessed by index (not ID) using values from 0

- *
- * A parameter ID has two parts, a type and an int (only used by some types).
- *
- * This is a bit more ugly than it could be, due to using the existing/legacy
- * ARDOUR::AutomationType:  GainAutomation, PanAutomation, SoloAutomation,
- * and MuteAutomation use only the type(), but PluginAutomation and
- * MidiCCAutomation use the id() as port number and CC number, respectively.
- *

-	 * <li>Transitivity: let f(x, y) and f(y, z) be true. We prove by assuming the contrary,

-	 *      <li> x == z which contradicts the assumption f(x, y) and f(y, x)

-	 *           of x is greater than the same ivar in z while all "previous" ivars
-	 *           are equal. That would imply that also in y all those "previous"
-	 *           ivars are equal and because if x.i > z.i it is impossible
-	 *           that there is an y that satisfies x.i < y.i < z.i at the same

-	RR approach may end up filling up a filesystem

-	Its therefore important to pay some attention to
-	the freespace in the filesystem holding each
-	directory as well. However, if we did that by
-	itself, we'd keep creating new files in the file
-	system with the most space until it was as full
-	as all others, thus negating any performance
-	benefits of this RAID-1 like approach.
-
-	So, we use a user-configurable space threshold. If
-	there are at least 2 filesystems with more than this
-	much space available, we use RR selection between them. 
-	If not, then we pick the filesystem with the most space.
