## Summary:

  # Urgrep - Universal Recursive Grep

  [![GNU ELPA version][elpa-image]][elpa-link]

  **Urgrep** is an Emacs package to provide a universal frontend for *any*
  grep-like tool, as an alternative to the built-in `M-x rgrep` (and other 
similar
  packages). Currently, [`ugrep`][ugrep], [`ripgrep`][ripgrep], [`ag`][ag],
  [`ack`][ack], [`git grep`][git-grep], and [`grep`][grep]/[`find`][find] are
  supported.

  ## Why Urgrep?

  #### One package, many tools

  No matter which tool you prefer, you can use it with Urgrep. If a new tool 
comes
  along, you won't need to find a new Emacs package for it.

  #### Rich minibuffer interface

  Easily manipulate per-search options with Isearch-like key bindings within the
  Urgrep minibuffer prompt.

  #### Seamless support for Tramp
