+dnl
+dnl Autoconf macro to check conditions for an HLT module
+dnl          - header dependencies
+dnl          - library dependencies
+dnl          - AliRoot availability
+dnl The macro also exports the --enable/--disable option for the
+dnl module.
+dnl
+dnl Synopsis:
+dnl
+dnl  ROOT_PATH([module],
+dnl            [headers], [additional CPPFLAGS],
+dnl            [libraries], [LD flags], [LIBS],
+dnl            [circ libraries], [LD flags], [LIBS])
+dnl
+dnl First argument is the module name.
+dnl
+dnl Arg 2 and 3 allow to check a list of header files and to specify
+dnl additional CPPFLAGS which might be necessary to perform the checks.
+dnl 
+dnl Arg 4 to 6 allow to check a list of libraries, with additional
+dnl LDFLAGS and LIBS to be specified.
+dnl
+dnl Arg 7 to 9 is the same for libraries with circular dependencies
+dnl among each other.
+dnl
+dnl Return:
+dnl enable_module=yes
+dnl   - AliRoot was found &&
+dnl   - header files found &&
+dnl   - module not disabled
+dnl
+dnl enable_module=no...requires.AliRoot
+dnl   - AliRoot not found
+dnl
+dnl enable_module=missheader
+dnl   - one of the specified header files is missing
+dnl
+dnl Libraries are probed and the variable ALIHLTMODULE_LIBS is set to
+dnl all libraries which could be found.
