Targets syntax
The targets file is line-based. Its syntax is:
HTTP_METHOD url
$ body
The body line is optional. The rules for what is considered to be a body line are:
- If something starts with
$(dollar-sign and space), it's a body - If the line is literally
{}, it's an empty body
A missing body line is taken to mean an empty request body. Point (2) is there for backwards-compatibility.
