This diagram shows the top-level structure of the program flow.
The rounded rectangles indicate major computational process in the program flow.
The dashed lines indicates the program flow between states.
The arrowhead shows the direction of the program flow.
Inputs to a process flow from the left to a process.
Outputs from a process flow to the right from a process.
Folder icons represent directories.
Source directories have their pathnames to the left of the icon,
Destination directories have their pathnames to the right of the icon.
Data flow is indicated by solid lines with the arrowheads indicating the source of the data flow.
The data file(s) read or written to/from the directory is indicated by
file
icons above the data flow arrow, with their name to the left or right depending on whether they are being read or written.
Multiple files are represented by the
multiple files
icon which have a thicker outline and have an '*' in their name.
Data flows directly from/to a file icon have no special meaning; the full path to the file is given in it's name so there is no need for a directory icon.
