Simple Perl Package Manager

This release condenses the default 'steps' down to configure,
build, and install. Running of sysfind and sysdiff is now part of
the installation process, and installwatch is used if it is installed.
Installwatch logs are now used by default for the "final"
package file listing, but a copy of the listing produced by sysdiff
is also saved for comparison. Installwatch package listing are
now mostly reliable, but beware (i.e. compare to sysdiff's
output) for some packages, especially large packages such as
gcc which do "unusual" things when installing. The install scripts
were upgraded.
