This is all explained in my chapter in Richard Boulanger's book, the
chapter entitled "Language Extentions" (ch 5 I think)

However as you may not have a copy of the book to hand....

b       Resets the base clock for textually following events.  I use
it for repeated sections where I want an overlap with previous version
as it does not start a new section.  It is textual, and is expanded
before sorting.

v       Sets a scaling on the speed of the clock, again textually until
the end of the section or the next v command.  I use it for phase
music, where there is 1 theme played twice simultaneously at different
speeds.  As it is textual it is local unlike the t command

m       Sets a mark in the score which can be referenced by later n
directives

n       repeat a named section (ie from m to end of section).
Designed to simplify verse+chorus structures.

w is totally different and is used internally related to t
directives.  There is no reason to understand it as it shoudl not be
used.  Alternatively, read the cod if you want to know!
