===================
*** Indivisible ***
===================
Indivisible is an optimized prime number generator and tester written in Rust.

# Building
----------
To build the project you will require the Rust compiler and build
system, `cargo`. At which point you simply run `cargo build` in the root
directory of the project. To create an optimized release build append
the `--release` flag to the previous command.

# Usage
-------
The purpose of Indivisible is to find the nth prime and all the primes
before it. The basic usage is `indivisible <n>` where `n` is the ordinal
of the prime you'd like to find. To display all primes before `n`, you
can run verbose mode by using the `--verbose` or simply `-v` option.

Since Indivisible generates primes using previously computed primes, you
can also import prime numbers previously computed with the `--import` or
`-i` option. To store already computed primes you are expected to use
piping like any UNIX user would expect. Here is an example:

  # store first 100 primes in ./primes
  indivisible -v 100 > ./primes
  # appends next 400 primes
  indivisible -i ./primes -v 500 >> ./primes
  # display the 600th prime
  indivisible -i ./primes 600
