// NSIS_SUPPORT_MESSAGEBOX enables support for MessageBox
#define NSIS_SUPPORT_MESSAGEBOX
// Added by Ximon Eighteen 5th August 2002
// If this is uncommented the following changes/new features are
// turned on :-
// - At the start of compilation a directory called dlls in
// the directory where makensis.exe is running from will be
// scanned for .dll files.
// - Any functions in the detected dll files that are exported
// by name will be remembered. These names are then legal
// command keywords in an NSIS script.
// - Any command that is unrecognised is checked against the
// list of external dll command names. If matched the dll will
// be packed into the installer.
// - On the installer machine (rather than the build machine)
// on first use of a command that requires a plugin dll that
// dll will be extracted to the temporary directory with a
// temporary file name.
// - Any parameters following the command will be pushed onto
// the stack in left to right order.
// - The command will then be invoked in the dll as if
// "CallInstDLL dll command" had been invoked.
// - When the installer exits any extracted temporary dlls will
// be deleted.
//#define NSIS_CONFIG_PLUGIN_SUPPORT
