# If not using package management but using this anyway, then think about how
# you perform upgrades and revert them. You should consider the benefit of
# embedding the Exim version number into LOOKUP_MODULE_DIR, so that you can
# maintain two concurrent sets of modules.
+#
+# *BEWARE*: ability to modify the files in LOOKUP_MODULE_DIR is equivalent to
+# the ability to modify the Exim binary, which is often setuid root! The Exim
+# developers only intend this functionality be used by OS software packagers
+# and we suggest that such packagings' integrity checks should be paranoid
+# about the permissions of the directory and the files within.

# To build a module dynamically, you'll need to define CFLAGS_DYNAMIC for

# In either case you must specify the library link info here. If the
# PCRE header files are not in the standard search path you must also
# modify the INCLUDE path (above)
-# The default setting of PCRE_LIBS should work on the vast majority of
-# systems

+# Use PCRE_CONFIG to query the pcre-config command (first found in $PATH)
+# to find the include files and libraries, else use PCRE_LIBS and set INCLUDE
