# 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
