Example

I'm nobody! Who are you?

Are you nobody, too?

Then there's a pair of us - don't tell!

They'd banish us, you know.

How dreary to be somebody!

How public, like a frog

To tell your name the livelong day

To an admiring bog!

case sensitive:

deno run --allow-env --allow-read main.ts to poem.txt

output:

Are you nobody, too?

How dreary to be somebody!

case insentitive:

IGNORE_CASE=1 && deno run --allow-env --allow-read main.ts to poem.txt

output:

Are you nobody, too?

How dreary to be somebody!

To tell your name the livelong day

To an admiring bog!
