The solview application is a simple java utility to display information about a Solaris 10 (or later) system. Specifically, it shows:

New! Version 0.44 - download - code cleanups, and te individual panels of solview can now be launched in isolation. Try 'solview services', 'solview information'.

So here's some of the long output, akin to pkginfo -l:

And here's the file view, showing me the cluster and install metaclusters that /sbin/ifconfig is a member of:

To try it out, download this file, gunzip and untar it, cd to the solview-x.x directory, and run:
./solview
Any comments or suggestions are welcome.
Solview can show information about a package, and also shows what other packages are a necessary prerequisite for the package to function correctly. The contents file is parsed to show how many files are present in a package or cluster, and how much space they occupy.
You can also see whether a software cluster is fully, partially, or not installed. This is simply calculated from whether all, some, or none of its constituent packages are installed.
You can browse the filesystem tree to see which package or packages a given file is a member of. (This is, unfortunately, confused by symbolic links.)
You can also see details about a Solaris distribution. Simply add the location of the Product directory as an argument to the solview command.
And given a distribution, you can build a jumpstart profile.
