# DTrace is supported on linux, solaris, mac, and bsd. There are
11+
# three object files associated with DTrace support, but they're
12+
# not all used all the time:
13+
#
14+
# node_dtrace.o all configurations
15+
# node_dtrace_ustack.o not supported on mac and linux
16+
# node_dtrace_provider.o All except OS X. "dtrace -G" is not
17+
# used on OS X.
18+
#
19+
# Note that node_dtrace_provider.cc and node_dtrace_ustack.cc do not
20+
# actually exist. They're listed here to trick GYP into linking the
21+
# corresponding object files into the final "node" executable. These
22+
# object files are generated by "dtrace -G" using custom actions
23+
# below, and the GYP-generated Makefiles will properly build them when
24+
# needed.
