Changes in version 1.7: Changes in version 1.8:
Minor changes have been made. Lunzip now verifies that the output file is regular when "low memory"
mode is requested.
The targets "install-compress", "install-strip-compress", and Some error messages have been adjusted to be identical to those of
"install-man-compress" have been added to the Makefile. lzip-1.17.
