$prog_name v$version is a very simple addressbook written in sh
$prog_name usage:
$prog_name {add | find | rm} key1=value1 [key2=value2 [...]]
$prog_name list
Where key can be any of are:
name, surname, code, phone, address, position, email, homepage, date,
comment
Comment key is special and must be last key used. Comment value may
contain spaces.
Values and commands are case sensetive, keys are not.
Use of | character is forbidden as it's used as field seperator in
addressbook.
