+# To include resolv in the LIBS="" list for SUN 3, 4 or Solaris OS,
+# point RESOLVLIB to that library.  You need this if you get the message

+# If you are adding direct wais access you must fill in the
+# location of wais.a, client.a and the standard math library, libm.a.
+# You can pick up the most current freeWAIS sources from
+#	ftp://ftp.cnidr.org/pub/NIDR.tools/freewais
+# If you are using freeWAIS-0.202 or older, include -DDECLARE_WAIS_LOGFILES

+
+# !!!!!!!!!!!!! SLANG Support (For color version of Lynx). !!!!!!!!!!!!!!!!
+# The slang library is an alternative to curses, developed by John E. Davis
+# (davis@space.mit.edu).  Version 0.99-27 or higher is available from
+#	ftp://space.mit.edu/pub/davis
+# It provides color support for Lynx.
+
+# !!!!!!!!!!!!! NCURSES Support (For color version of Lynx). !!!!!!!!!!!!!!
+# If you need ncurses, the latest version can always be found
+# in https://invisible-island.net/ncurses/
+# or https://ftp.gnu.org/pub/gnu/
+
+# Also be sure to check out the compilation symbols in userdefs.h
+# before building Lynx!
+
+# If you apply patches which require linking to site-specific libraries, set
+# SITE_LIBS to those libraries.
+SITE_LIBS= # Your libraries here
+
+# Set SITE_LYDEFS to one or more of the defines for the WWW Library:
+SITE_LYDEFS = # Your defines here
+
+# Set SITE_DEFS to one or more of the defines for lynx below:
+SITE_DEFS = # Your defines here
+
+# defines for which there are no configure options:
+# -DIGNORE_CTRL_C  Define if Control-C shouldn't exit lynx.
+# -DNO_RULES       Disables CERN-style access rules (see lynx.cfg).
+#
+# if you are linking to freeWAIS-0.202 or older, you should define this
+# in SITE_DEFS
+#
+# -DDECLARE_WAIS_LOGFILES
+#
+# if you have an SVR4 system with the "type any key" problem, try defining
+# this in LYFLAGS (SITE_LYDEFS) and SITE_DEFS
+#
+# -DSVR4_BSDSELECT
+#
+# Many other defines have configure options  (see INSTALLATION, Section II-1c.):
