+Source text parsing, lexing, and AST related functionality for
+[Deno](https://deno.land).
+
+```rust
+use deno_ast::parse_module;
+use deno_ast::MediaType;
+use deno_ast::ParseParams;
+use deno_ast::SourceTextInfo;
+
+let source_text = "class MyClass {}";
+let text_info = SourceTextInfo::new(source_text.into());
+let parsed_source = parse_module(ParseParams {
+  specifier: "file:///my_file.ts".to_string(),
+  media_type: MediaType::TypeScript,
+  text_info,
+  capture_tokens: true,
+  maybe_syntax: None,
+  scope_analysis: false,
+}).expect("should parse");
+
+// returns the comments
+parsed_source.comments();
+// returns the tokens if captured
+parsed_source.tokens();
+// returns the module (AST)
+parsed_source.module();
+// returns the `SourceTextInfo`
+parsed_source.text_info();
