Lets you auto-format source code in many languages using the same
command for all languages, instead of learning a different elisp
package and formatting command for each language. Just do M-x
format-all-buffer
and it will try its best to do the right thing.

You will need to install external programs to do the formatting. If
format-all-buffer
can't find the right program, it will try to tell
you how to install it.
A local minor mode called format-all-mode
is available to format
code on save. Please see the documentation for that function for
instructions.
There are currently no customize variables, since it's not clear what approach should be taken. Please see GitHub issues for discussion.
Many of the external formatters support configuration files in the source code directory to control their formatting. Please see the documentation for each formatter.
New external formatters can be added easily if they can read code from standard input and format it to standard output. Feel free to submit a pull request or ask for help in GitHub issues.
GitHub issues are preferred. Email is also ok.
Feature requests are welcome. If you are interested in doing anything beyong just adding new formatters in the current framework, please discuss in issues before writing code, since there are big unresolved questions about where the project should go from here.
atom-beautify sports a very impressive set of formatters. We should aspire to that level of coverage for Emacs.
Unibeautify is a project to provide one shell command to run all beautifiers. atom-beautify will be rewritten to be based on it. Perhaps we should be too, once it stabilizes.
