# Structure of File Contents

Lines beginning with `#` are not necessary for parsing and can be thought of as
comments. All other non-empty lines are build of space-separated fields and
start with a string that identifies the parameter the line is dedicated to. If
one number follows, it denotes the value of the parameter. If two numbers
follow, the parameter is a mapping and the first number denotes the preimage and
the following the value. Timesteps, vehicles and reservations are identified
with integers starting from 1.

Below is a specification. The expression `<...>` is a placeholder for a number.
Only exception: `<timestep-range>` is a string of the form `<a>-<b>` and
represents all timesteps from a to b, including a and b. Expressions in curly
braces (`{...}`) may be repeated arbitrarily often (including zero times). The
bar `|` denotes a choice.

    # Timesteps
    tmax <tmax>
    DeltaT <dt>
    { Esurmax <t> <Esurmax> }

    # Vehicles
    n <n>
    Pmax <Pmax>
    Ecap <Ecap>
    { E0 <vehicle> <E0> }
    { Tavail <vehicle> { <timestep> | <timestep-range> } }

    # Reservations
    rmax <rmax>
    { tstart <reservation> <tstart> }
    { tend <reservation> <tend> }
    { Eres <reservation> <Eres> }
      
    # Costs
    cuncov <cuncov>
    alpha <alpha>
    { c <t> <c> }
