"# General grammatical elements and rules:\n"
"#\n"
"# * Strings with double quotes (\") denote SOFT KEYWORDS\n"
"# * Strings with single quotes (') denote KEYWORDS\n"
"# * Upper case names (NAME) denote tokens in the Grammar/Tokens file\n"
"# * Rule names starting with \"invalid_\" are used for specialized syntax errors\n"
"#     - These rules are NOT used in the first pass of the parser.\n"
"#     - Only if the first pass fails to parse, a second pass including the invalid\n"
"#       rules will be executed.\n"
"#     - If the parser fails in the second phase with a generic syntax error, the\n"
"#       location of the generic failure of the first pass will be used (this avoids\n"
"#       reporting incorrect locations due to the invalid rules).\n"
"#     - The order of the alternatives involving invalid rules matter\n"
"#       (like any rule in PEG).\n"
"#\n"
"# Grammar Syntax (see PEP 617 for more information):\n"
"#\n"
"# rule_name: expression\n"
"#   Optionally, a type can be included right after the rule name, which\n"
"#   specifies the return type of the C or Python function corresponding to the\n"
"#   rule:\n"
"# rule_name[return_type]: expression\n"
"#   If the return type is omitted, then a void * is returned in C and an Any in\n"
"#   Python.\n"
"# e1 e2\n"
"#   Match e1, then match e2.\n"
"# e1 | e2\n"
"#   Match e1 or e2.\n"
"#   The first alternative can also appear on the line after the rule name for\n"
"#   formatting purposes. In that case, a | must be used before the first\n"
"#   alternative, like so:\n"
"#       rule_name[return_type]:\n"
"#            | first_alt\n"
"#            | second_alt\n"

"#   Optionally match e.\n"
"# e*\n"
"#   Match zero or more occurrences of e.\n"
"# e+\n"
"#   Match one or more occurrences of e.\n"
