/** @page chk_support Checking whether an URL is supported

Checking whether the available @ref m_script or @ref pl_script collection
accepts the URL may be done either with or without an internet connection.

Note, however, that most checks will return the "no support" error
with the @ref sh_url and the @ref QUVI_SUPPORTS_MODE_OFFLINE, as this
would normally require resolving the URL over the Internet, first.

@code
QuviBoolean r = quvi_supports(q, URL,
                              QUVI_SUPPORTS_MODE_OFFLINE,
                              QUVI_SUPPORTS_TYPE_MEDIA);
@endcode

Similar to the above but do an online check, instead:

@code
QuviBoolean r = quvi_supports(q, URL,
                              QUVI_SUPPORTS_MODE_ONLINE,
                              QUVI_SUPPORTS_TYPE_MEDIA);
@endcode

The above two examples limit the check to @ref m_script support only.
The example below tells the library to check the URL against
@ref m_script and @ref pl_script collections.

@code
QuviBoolean r = quvi_supports(q, URL,
                              QUVI_SUPPORTS_MODE_ONLINE,
                              QUVI_SUPPORTS_TYPE_ANY);
@endcode

@sa QuviSupportsMode
@sa QuviSupportsType

The available @ref m_script and @ref pl_script collection determines which
websites are supported by the library.
