Mentioned by Neil in this code review

Silent build with Automake 1.11 (with fallback support for older versions)

Add this to configure.ac, below AM_INIT_AUTOMAKE():

m4_ifdef([AM_SILENT_RULES], [AM_SILENT_RULES([yes])])

Examples request

• an example for adding and handling --enable/disable-foo
• an example for adding an "option-list" (e.g. ./configure --with-test=actions,monitor,dialog)
