+Justfile grammar is a little weird. Because of the freeform
+nature of recipe bodies, we don't tokenize them with the
+same rules as the rest of the justfile. Instead the
+tokenizer will emit a INDENT at the beginning of a recipe
+body, one or more LINEs, which match everything after the
+INDENT whitespace, and a DEDENT at the end.
+
+Thus the lexer is context sensitive, which is a little
+gross.
+
+tokens:
+
+NAME    = /[a-z]((_|-)?[a-z0-9])*/
+EOL     = /\n|\r\n/
+COMMENT = /#[^!].*/
+COLON   = /:/
+INDENT  = emitted when indentation increases
+DEDENT  = emitted when indentation decreases
+LINE    = /.*/ only emitted between INDENT/DEDENT pairs, doesn't include INDENT whitespace
+EOF     = emitted at the end of input
+
+grammar:
+
+justfile = item* EOF
+
+item = COMMENT
+     | recipe
+     | EOL
+
+assignment = NAME EQUALS expression COMMENT? EOL
+
+expression = STRING
+
+recipe = NAME+ COLON NAME* EOL (INDENT LINE+ DEDENT)?
