XStatic-D3
|
||||
--------------
|
||||
|
||||
Hogan JavaScript library packaged for setuptools (easy_install) / pip.
|
||||
|
||||
This package is intended to be used by **any** project that needs these files.
|
||||
|
||||
It intentionally does **not** provide any extra code except some metadata
|
||||
**nor** has any extra requirements. You MAY use some minimal support code from
|
||||
the XStatic base package, if you like.
|
||||
|
||||
You can find more info about the xstatic packaging way in the package `XStatic`.
