Re: [Bug-gsl] Missing constants

[Evgeny Kurbatov]

Hi, Brian!

I remember I promised to take care on electromagnetic constants but I
absolutely have no time for that.  The blitzkrieg tactics didn't bring
results because I can't examine the emacs's lisp system-of-units
transformation methods.  If anyone could fix it I'd prepare all the
constant values and/or transformation formulas for her.
