var msg = require('mkmsg')
  , ast = require('mkast');
ast.src('This is a markdown paragraph.')
  .pipe(msg())
  .pipe(ast.stringify({indent: 2}))
  .pipe(process.stdout);

Append the default generator message:

mkcat README.md | mkmsg | mkout

Append a custom message:

mkcat README.md | mkmsg -m "Commit: $(git rev-parse HEAD)" | mkout
