+# [CHANGEME]
+# Default flags:
+# Change XCFLAGS if you don't like what Config puts there.  Same with
+# IRCDLIBS.
+#
+# If you are configuring by hand, try "-O -g" for XCFLAGS, and leave
+# IRCDLIBS blank.  If that fails, try recomendations below.
+#
+XCFLAGS=-O2
+IRCDLIBS=-lcrypt -lresolv -lz
+
+# [CHANGEME]
+# IRCDMODE is the mode you want the binary to be.
+# The 4 at the front is important (allows for setuidness)
+#
+# WARNING: if you are making ircd SUID or SGID, check config.h to make sure
+#          you are not defining CMDLINE_CONFIG 
+IRCDMODE = 711

+# [CHANGEME]
+# IRCDDIR must be the same as DPATH in include/config.h
