# X11 driver
# requires installed XFree86

# PNG device driver
# requires PNG and Z libraries (not part of gnuplot)

# GNU_ReadLine support
# requires GNU readline library (static or DLL; not part of gnuplot)
GNU_RL=1

# DEBUGging support
# creates binaries suitable for debugging. Some bugs may come and go
# as opposed to a production build since we lower the optimization level
# DEBUG=1

# MOUSE support for PM terminal
