+# pyAltiForce
+Python Parsing for AltiForce GoPro Backpack CSVs
+
+The CSV file is processed and a plot of time vs. total acceleration is displayed.
+
+## Usage
+Calling `pyAltiForce` from the command line with no arguments opens a file selection GUI for the user to select a single CSV file to process and display.
+
+Calling `pyAltiForce` with the optional `-f` or `--file` flag will allow the user to specify a single CSV file to process.
+
+Examples Include:
+
+    python pyAltiForce -f './Data/GOPR0024.CSV'
+    python pyAltiForce --file 'C:/My Data/GOPR0024.CSV'
