| dnl FEATURE-NAME - feature name; library and header files are treated |
| dnl as feature, which we look for |
| dnl LIB-NAME - library name as in AC_CHECK_LIB macro |
| dnl LIB-FUNCTION - library symbol as in AC_CHECK_LIB macro |
| dnl HEADER-NAME - header file name as in AC_CHECK_HEADER |
| dnl ACTION-IF-FOUND - when feature is found then execute given action |
| dnl ACTION-IF-NOT-FOUND - when feature is not found then execute given action |
| dnl EXTRA-LDFLAGS - extra linker flags (-L or -l) |
| dnl EXTRA-CPPFLAGS - extra C preprocessor flags, i.e. -I/usr/X11R6/include |
