Since ncurses now builds and installs the shared libraries the
ncurses_so package is no longer needed.

A few utilities that I've been using (such as tig) need utf-8 support to
work correctly.

Now uses autogen.sh and correctly finds ncurses without explictly
passing an include path to CPPFLAGS.

Dstat is a versatile replacement for vmstat, iostat, netstat and ifstat.
Dstat overcomes some of their limitations and adds some extra features,
more counters and flexibility. Dstat is handy for monitoring systems
during performance tuning tests, benchmarks or troubleshooting.

iftop does for network usage what top(1) does for CPU usage. It listens
to network traffic on a named interface and displays a table of current
bandwidth usage by pairs of hosts. Handy for answering the question "why
is our ADSL link so slow?".

Tested as working on Samsung XE50013-K01US.

The UnRar package contains a RAR extraction utility used for extracting
files from RAR archives. RAR archives are usually created with WinRAR,
