    wakatime.projects.projectmap
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Use the ~/.wakatime.cfg file to set custom project names by
    recursively matching folder paths.
    Project maps go under the [projectmap] config section.

    For example:

        [projectmap]
        /home/user/projects/foo = new project name
        /home/user/projects/bar = project2

    Will result in file `/home/user/projects/foo/src/main.c` to have
    project name `new project name`.
