## Summary:

  1 SVG Library
  ═════════════

    svg-lib is an Emacs library that allows to create and display various
    SVG objects, namely tags, icons, buttons, progress bars, progress pies
    and dates. Each object is guaranteed to fit nicely in a text buffer
    ensuring width is a multiple of character width and height a multiple
    of character height.


  2 Installation
  ══════════════

    ┌────
    │ M-x package-install RET svg-lib RET
    └────


  3 Quick start
  ═════════════

    For the impatient, evaluate the following expression:

    ┌────
    │ M-: (insert-image (svg-lib-tag "TODO"))
    └────

    This should insert a SVG tag displaying "TODO" in a rounded box whose
    size is exactly 5 characters wide (because of padding).
