"`company-mode' back-end for `yasnippet'.
|

This back-end should be used with care, because as long as there are
|

|
|
snippets defined for the current major mode, this back-end will always
|
||
|
|
shadow back-ends that come after it. Recommended usages:
|
||
|
|
|
||
|
|
* In a buffer-local value of `company-backends', grouped with a back-end or
|
||
|
|
several that provide actual text completions.
