More of an anti-pattern than a pattern. A single file executable means
that when you have a security update, instead of patching one library,
you have to patch all fifty applications that include that library.

The machine I'm currently on has a 5.6K Python executable:
[steve at ando ~]$ ls -lh /usr/bin/python*
-rwxr-xr-x 2 root root 5.6K Jan 9 2013 /usr/bin/python
lrwxrwxrwx 1 root root 6 Jan 22 2013 /usr/bin/python2 -> python
-rwxr-xr-x 2 root root 5.6K Jan 9 2013 /usr/bin/python2.4
but that doesn't include libpython:
[steve at ando ~]$ ls -lh /usr/lib/libpython2.4.so*
lrwxrwxrwx 1 root root 19 Jan 22 2013 /usr/lib/libpython2.4.so -> libpython2.4.so.1.0
-r-xr-xr-x 1 root root 1.1M Jan 9 2013 /usr/lib/libpython2.4.so.1.0
or the standard library.
