A blackbox style conversion utility
Blackbox 0.70+ is committed to fully support the style syntax of previous versions, thus allowing older styles to be loaded and used. However, if one of your favorite styles seems 'broken', you can try this utility.
bstyleconvert reads given old Blackbox style file(s) (<= 0.65) and produces according new style file(s), appending '-new' to original filename(s).
This program does not support (nor need) any options.
