Our hero, a mathematician, is writing notes in LaTeX and needs to convert it to a format that her blog platform accepts. She’s used to using dollar sign delimiters for math mode, but her blog requires \ \ and \ \. Find-and-replace fails because it doesn’t know about which dollar sign is the start and which is the end. She knows there’s some computer stuff out there that could help, but she doesn’t have the damn time to sort through it all.
