We need a simple and generic way to parse an email file. Since it would be hard to include and maintain an external library, create an simple email parser subroutine to parse an email file. Signed-off-by: Samuel GROOT <redacted> Signed-off-by: Tom RUSSELLO <redacted> Signed-off-by: Matthieu MOY <redacted> --- We chose to create our own simple email parser and only use it for the "quote email" feature to pave the way for the refactorization of the patch parser [1] that may come after our current school project.
