New Features
============
1. The PT_NO_INSTALL_PACKAGE make variable will cause a port to always
be compiled, instead of being installed from a package. It cannot
be used in combination with the -PP/--packages-only option. [1]
2. All user input is now wrapped in a verification routine to make
sure that yes means yes, etc.
3. The -e, -s, --clean-distfiles, --clean-packages, --check-depends
and --check-port-dbdir features can now take -y and -n options to
answer "yes" or "no" respectively to all user dialogs. This also
allows me to deprecate the horribly hacky --clean-distfiles-all and
--clean-packages-all in favor of -y.
4. If using a separate WRKDIRPREFIX, when the run is over use find to
clean out the empty directories that are left behind by the ports
infrastructure.
5. If PM_PACKAGES is set, don't bother with build depends [2]
Small Fixes And Improvements
============================
1. Update usage() in the script and the man page for the new features,
and improve the consistency between the two.
2. When we enter -PRERELEASE phase the package-finding code should
still be looking at -stable. [3]
3. Fix some bugs with -r:
* In certain situations dependent ports that were otherwise
up to date would be missed.
* For the purpose of not rebuilding the parent port when -R
is used we only care about the dependencies of the parent
port being up to date.
4. Error handling for INDEX fetch
5. The -e, -s, -l, -L, --list-origins, and --check-depends features
all work fine without a ports tree
* In -e and -s, delete_dist_list() requires the ports tree, so
if the user didn't use -D imply it when the ports tree is
missing, and hide delete_dist_list() behind that test
6. pdb and port_dbdir need default values for usage()
