Normally, a combination of looking at the first few lines of the script
(e.g.
$ head /etc/init.d/cpuspeed
#!/bin/sh
# Startup script for cpuspeed
#
# chkconfig: 12345 06 99
# description: Run dynamic CPU speed daemon
...)

and the description for the package (e.g.
$ rpm -qif /etc/init.d/cpuspeed
<snip>
Description :
kernel-utils contains several utilities that can be used to control
the kernel or your machines hardware. Included are
* dmidecode - gives information about the bios and motherboard revisisons
* microcode_ctl - updates the microcode on Intel cpu's
* smartctl - monitor the health of your disks
)

gives you a basic idea of what they do. "Typical" is difficult, because
there are so many different workloads, and their users all think them
"typical" or "fairly typical".

What would you want that can't be got this way? (Pointers to what I've
just done?)
