+# SYNOPSIS
+#
+# AX_CFLAGS_HPUX_OPTION (optionflag [,[shellvar][,[A][,[NA]]])
+#
+# DESCRIPTION
+#
+# AX_CFLAGS_HPUX_OPTION(-Afresh) would show a message as like
+# "checking CFLAGS for hpux/cc -Afresh ... yes" and adds the
+# optionflag to CFLAGS if it is understood. You can override the
+# shellvar-default of CFLAGS of course. The order of arguments stems
+# from the explicit macros like AX_CFLAGS_WARN_ALL.
+#
+# The cousin AX_CXXFLAGS_HPUX_OPTION would check for an option to add
+# to CXXFLAGS - and it uses the autoconf setup for C++ instead of C
+# (since it is possible to use different compilers for C and C++).
+#
+# The macro is a lot simpler than any special AX_CFLAGS_* macro (or
+# ac_cxx_rtti.m4 macro) but allows to check for arbitrary options.
+# However, if you use this macro in a few places, it would be great
+# if you would make up a new function-macro and submit it to the
+# ac-archive.
+#
+# - $1 option-to-check-for : required ("-option" as non-value)
+# - $2 shell-variable-to-add-to : CFLAGS (or CXXFLAGS in the other case)
+# - $3 action-if-found : add value to shellvariable
+# - $4 action-if-not-found : nothing
+#
+# note: in earlier versions, $1-$2 were swapped. We try to detect the
+# situation and accept a $2=~/-/ as being the old
+# option-to-check-for.
+#
+# see also: AX_CFLAGS_GCC_OPTION for the widely used original
+# variant.
