automake 1:1.16.3-2ubuntu1 (arm64 binary) in ubuntu impish

 Automake is a tool for automatically generating `Makefile.in's from
 files called `Makefile.am'.
 .
 The goal of Automake is to remove the burden of Makefile maintenance
 from the back of the individual GNU maintainer (and put it on the back
 of the Automake maintainer).
 .
 The `Makefile.am' is basically a series of `make' macro definitions
 (with rules being thrown in occasionally). The generated
 `Makefile.in's are compliant with the GNU Makefile standards.
 .
 Automake 1.16 fails to work in a number of situations that Automake
 1.11, and 1.15 did, so some previous versions are available as separate
 packages.
