_opt_Debug=0
# 0 = standard build
# 1 = debug build
# 2 = debug build with slow compile to make compile errors easy to see
# Debug builds must be launched from the command line to allow
# sudo to change a system setting. If you need to keep the desktop file
# set the option below.

_opt_clang=0
# 0 = gcc
# 1 = clang

_opt_keepdesktop=0
# 0 = normal
# 1 = install desktop file even in debug modes. This is dangerous as launching sudo in a .desktop crashes the DE

_opt_fdpp=0
# 0 = use freedos
# 1 = use fdpp and comcom32 (boot only, freedos is still used for utilities)
