+DESIGN DECISIONS
+----------------
+
+HELP
+~~~~
+--help or -h is used for help. We do not reserve the bare word "help", which
+for example the ip command does. Reserving a bare word like help quickly
+becomes cumbersome to handle in the code. It might be simple to handle
+when it's passed early in the command chain like "ip addr help". But when
+the user tries to pass "help" further down this requires manual checks and
+special treatment. For example, at the time of writing this tool, it's
+possible to create a vlan named "help" with the ip tool, but it's impossible
+to remove it, the command just shows help. This is an effect of treating
+bare words specially.
+
+Help texts are not dynamically generated. That is, we do not pass datastructures
+like command list or option lists and print them dynamically. This is
+intentional. There is always that exception and when it comes to help texts
+these exceptions are normally neglected at the expence of usability.
+
+KEY-VALUE
+~~~~~~~~~
+All options are key-values. There are both drawbacks and benefits to this.
+The main drawback is that it becomes more to write for the user and
+information might seem redundant. The main benefits is scalability and code
+simplification. Consistency is important.
+
+Consider this.
+1. tipc link set priority PRIO link LINK
+2. tipc link set LINK priority PRIO
+
+Link might seem redundant in (1). However, if the command should live for many
+years and be able to evolve example (2) limits the set command to only work on a
+single link with no ability to extend. As an example, lets say we introduce
+grouping on the kernel side.
+
+1. tipc link set priority PRIO group GROUP
+2. tipc link set ??? priority PRIO group GROUP
+
+2. breaks, we can't extend the command to cover a group.
+
+PARSING
+~~~~~~~
+Commands are single words. As an example, all words in "tipc link list" are
+commands. Options are key-values that can be given in any order. In
+"tipc link set priority PRIO link LINK" "tipc link set" are commands while
+priority and link are options. Meaning that they can be given like
+"tipc link set link LINK priority PRIO".
+
+Abbreviation matching works for both command and options. Meaning that
+"tipc link set priority PRIO link LINK" could be given as
+"tipc l s p PRIO l LINK" and "tipc link list" as "tipc l l".
+
+MEMORY
+~~~~~~
+The tool strives to avoid allocating memory on the heap. Most (if not all)
+memory allocations are on the stack.
+
+RETURNING
+~~~~~~~~~
+The tool could throw exit() deep down in functions but doing so always seems
+to limit the program in the long run. So we output the error and return an
+appropriate error code upon failure.
