Add a new port for pkg_trackinst 0.2,
a pkg-plist/pkgdb auto-generator for unpackaged softwares or unfinished
ports. It provides two commands:
Tracks installation of unpackaged software and writes pkgdb
entry using the install log. Then, it also creates a binary
package for the installed package.
Generates `pkg-plist' of a port in current directory automatically
by a test installation.
