"primary input, and transitions animate between the end of one file/pattern\n"

"A file is a triplet of filename, inpoint (in seconds) and\n"
"duration (in seconds). If the duration is 0, the full file length is used.\n\n"
"Patterns and transitions are triplets that begin with either \"+pattern\"\n"
