/// \brief Macro for assertion with customizable message

///

/// Macro for assertion with customizable message.  \param exp An

/// expression that must be convertible to \c bool.  If it is \c

/// false, then an assertion is raised. The concrete behaviour depends

/// on the settings of the assertion system.  \param msg A <tt>const

/// char*</tt> parameter, which can be used to provide information

/// about the circumstances of the failed assertion.

///

/// The assertions are enabled in the default behaviour.

/// You can disable them with the following code:

/// \code

/// #define LEMON_DISABLE_ASSERTS

/// \endcode

/// or with compilation parameters:

/// \code

/// g++ -DLEMON_DISABLE_ASSERTS

/// make CXXFLAGS='-DLEMON_DISABLE_ASSERTS'

/// \endcode

/// The checking is also disabled when the standard macro \c NDEBUG is defined.

///

/// The LEMON assertion system has a wide range of customization

/// properties. As a default behaviour the failed assertion prints a

/// short log message to the standard error and aborts the execution.

///

/// The following modes can be used in the assertion system:

///

/// - \c LEMON_ASSERT_LOG The failed assertion prints a short log

///   message to the standard error and continues the execution.

/// - \c LEMON_ASSERT_ABORT This mode is similar to the \c

///   LEMON_ASSERT_LOG, but it aborts the program. It is the default

///   behaviour.

/// - \c LEMON_ASSERT_CUSTOM The user can define own assertion handler

///   function.

///   \code

///     void custom_assert_handler(const char* file, int line,

///                                const char* function, const char* message,

///                                const char* assertion);

///   \endcode

///   The name of the function should be defined as the \c

///   LEMON_CUSTOM_ASSERT_HANDLER macro name.

///   \code

///     #define LEMON_CUSTOM_ASSERT_HANDLER custom_assert_handler

///   \endcode

///   Whenever an assertion is occured, the custom assertion

///   handler is called with appropiate parameters.

///

/// The assertion mode can also be changed within one compilation unit.

/// If the macros are redefined with other settings and the

/// \ref lemon/assert.h "assert.h" file is reincluded, then the

/// behaviour is changed appropiately to the new settings.
