Update README.md
ExecuteBuffer for that case if you already know the size of your rendered template.
Change ExecuteWriter to ExecuteBuffer
Fixes issue #64
Merge branch 'master' of github.com:flosch/pongo2
Change ExecuteWriter to ExecuteBuffer again
Update path for the cover-tool
Removed go tip support for travis temporarily until Go 1.4 is out.
Merge remote-tracking branch 'upstream/master'
Merge pull request #63 from fromYukki/master

New API-function: Template.ExecuteBuffer()
ExecuteBuffer() prevents pongo2 to allocate a new buffer for template output generation; instead, the API user can provide his own allocated buffer for performance reasons.
Slight doc change and removed one unnecessary intermediate function call.
Include tag with `if_exists` flag
Merge pull request #67 from fromYukki/master

Tags: `if_exists` flag for include tag
This change improves the execution speed by reducing the allocation count (not allocating a main output buffer anymore for template generation when using Template.ExecuteWriter). Instead, the function directly writes to the given io.Writer. This behavior is now default when using ExecuteWriter(); therefore I've removed ExecuteBuffer() again whose goal was the same. Updates #63 and fixes #65.
Backwards-incompatible API-Change  for custom tags: tag execution functions are not taking a buffer anymore; instead, they are taking the new TemplateWriter interface.
Activating 1.4 and tip tests again for travis
New API: Introduced Template.ExecuteWriterUnbuffered() to keep up with the Template.ExecuteWriter's promise "nothing is written on error".
Typo
Make use of Template.ExecuteWriterUnbuffered() in the tests.
Adding slice/array-support for Value.Contains().
Fixes #71
Merge remote-tracking branch 'upstream/master' into v3
