-# Parser
-
-A parser takes an array of tokens (produced by the scanner) in input and
-returns a node representing a syntax tree. A node is an object
-containing a kind, the corresponding token and the ordered references to
-descendent nodes.
-
-A goal is to make the parser generic enough so it can generate syntax
-trees for most of existing programming languages (no claim of generality
-yet), provided a small set of generating rules per language, and a small
-set of validating rules (yet to be defined) to detect invalid
-constructs.
-
-The input tokens are particular in the sense that they include classical
-lexical items such as words, separators, numbers, but also strings and
-nested blocks, which are resolved at scanning stage rather than parsing
-stage. See the scanner for more details.
-
-The language specification includes the following:
-
-- a scanner specification, to produce the set of possible tokens.
-- a map of node specification per token name. The node specification
-  defines some parameters influing how the tree is generated.
-
-## Development status
-
-A successful test must be provided to check the status.
