Indeed, such might be "c-files" instead of b-files (cf. there are
already things like a-files for gappy ror "work-in-progress" versions of
what might once become a fully grown b-file).
A proposed upload format might be to have a reasonable max line length
(e.g. about 100 chars) and allow space for optional grouping.
Thus one prominent c-file might start
3.14159 26535 89793
23846 26433
I would suggest a simple script (e.g. perl) to create a c-file from an
existing b-file and the %e line.
This can work even with a badly offset b-file and even with a wrong %O
line - I guess the human readable form in the %e line is less error
prone with respect to correct offset value than both %O line and b-file
content.
