"""{escher} -- one-file key-value storage.

What?
  This is a toy application to manage persistent key-value string data.
  The file {escher} is *both* the application and its data.
  When you run any of the commands below, the file will be executed and,
  after data change, it will rewrite itself with updated data.
  You can copy the file with whatever name to create multiple datasets.

/* Limiarização de imagens utilizando OpenCV.
 *
 * Este programa implementa uma função genérica para limiarização de
 *  imagens em escala de cinza.
 *
 * Utilização: thresh file threshold below above
 *  *file - Nome do arquivo da imagem de entrada.
 *  *threshold - Valor real do limiar, no intervalo [0, 1].
 *  *below - Valor real que deve substituir valores abaixo do (ou iguais ao)
 *   limiar, no intervalo [0, 1].
