chids - execute a command with different uid, gid and supplementary groups list

it is nicer if you use the same option order in the synopsis section as in the
name section, same with the options section.

chids [-g <group>] [-s <group>[:<group>*] [-u <user>] <cmd> <arg>*
->
chids [-u <user>] [-g <group>] [-s <group>[:<group>*] <cmd> <arg>*

Do you have any nice example use for this program ?

$ ../../bin/chids 
chids[19750]: Usage: chids [-g <group>] [-s <group>[:<group>*] [-u <user>] <cmd> <arg>*
chids[19750]:     Execute a command with different uid, gid and supplementary groups list.
chids[19750]:     If a user was specificed via -u, the process gid will be set to the primary
chids[19750]:     group of this user unless -g was also provided and the supplementary groups
chids[19750]:     list will be initialized as for this user unless -s was also provided.

An empty line after line 2 would make this easier to read.
