From the automake manual, section on the "silent-rules" option: ``You can use the predefined variable $(AM_V_GEN) as a prefix to commands that should output a status line in silent mode, and $(AM_V_at) as a prefix to commands that should not output anything in silent mode. When output is to be verbose, both of these variables will expand to the empty string.''
Could we find a better name than $(AM_V_at)? - $(AM_V_SILENT) is nice, but also a bit too long. I wouldn't mind, but some people dislike long names for often-used variables. - $(SILENT) is shorter, but too much invasive of the user namespace. I'd strongly advise against it. - Other suggestions? If we find such a better name, we should then deprecate $(AM_V_at), but *not* remove it: it should be kept for backward-compatibility (probably for quite a long time).
