The main BSP toolbar can be configured with "bspbars.cfg" in the Settings
directory.
The first non-comment line in the config must be "bars N", where N is the
number of toolbars to create. Each line after that follows the format:
bar [N] [Command | Separator]
"Bar" is required on the start of each line. "N" is the 1-based index of toolbar to
add a command to. "Separator" can be used instead of a command name to
create a spacer between groups of buttons.
Note: It is recommended to have no more than one of each button added to the
toolbar. Duplicate buttons will not be updated correctly because BSP stops
looking after finding the first one.
