Paco (pacKAGE oRGANIZER) is a simple, yet powerful tool to aid package management when installing programs from source code. It uses the LD_PRELOAD method to track package installations, and provides various options to keep the installed software organized. It's mainly a command line application but it has also an optional GTKMM interface.
This is the "progress" utility from NetBSD, ported to Linux and Solaris. The progress utility allows the file I/O of progresses to be monitored. It includes support for gzip-compressed files, so "progress -z -f file.tar.gz tar xf -" would show the progress of extracting file.tar.gz.
