How can I build an "installp format" file?

Jim Abbey has a tool called "lppbuild".
It is now available from "aixpdslib.seas.ucla.edu"
in either of

/pub/lppbuild/RISC/3.2/src/lppbuild.1.0.tar.Z
/pub/lppbuild/RISC/4.1/src/lppbuild.1.0.tar.Z

Both are identical and the procedures also work on 4.2.

Ciaran Diegnan has built a tool called
"mklpp". You can retrieve a copy (along with many other
smit-installable freeware packages) from .
