 ### Segment formatting
 `gwrite` uses `.format()` encoding which means that data elements must be encasulated in `{}` brackets. This provides a particular syntax token which differs from between elements.
 For example every element except `layer_join` and `segment_join` accepts the value of `index`. You would encode that in the text as `{index:d}` the d denotes an integer value. If you need to have a `{` value in your text you would encode that as `{{` likewise you would encode a `}` as `}}`.
 - `layer_start`: Accepts `index` the current layer number.
 - `layer_end`: Accepts `index` the current layer number.
-- `linecollection_start`: Accepts `index` the current linecollection number.
-- `linecollection_end`: Accepts `index` the current linecollection number.
+- `line_start`: Accepts `index` the current line number.
+- `line_end`: Accepts `index` the current line number.
 
 The segments accept a lot of values that may be useful statistics for various formats:
 * `index`: index of the particular coordinate pair. eg `{index:d}`
