DIST_COMMON += %VTEXI% %STAMPVTI%

## Don't give this rule a command (even '@:').
## %STAMPVTI% is always newer than %VTEXI%, so this rule is always
## triggered.  If you equip this rule with a command, GNU make will
## assume %VTEXI% has been rebuild in the current directory and
## discard any %VTEXI% file found in a VPATH search.
%VTEXI%: %MAINTAINER-MODE% %STAMPVTI%

## Depend on configure so that version number updates cause a rebuild.
## (Not configure.ac, because not all setups define the version number
## in this file.)
%STAMPVTI%: %TEXI% $(top_srcdir)/configure
## It is wrong to have %STAMPVTI% dependent on %DIRSTAMP%, because
## %STAMPVTI% is distributed and %DIRSTAMP% isn't: a distributed file
## should never be dependent upon a non-distributed built file.
## Therefore we ensure that %DIRSTAMP% exists in the rule.
## Use cp + mv so that the update of %VTEXI% is atomic even if
## the source directory is on a different file system.
