Dear GSL developers, First of all, thanks for all your work!
I have one minor complaint: every time I write new code that uses gsl_interp_bsearch() I end up opening gsl_interp.h and looking for this (very informative) comment: https://git.savannah.gnu.org/cgit/gsl.git/tree/interpolation/gsl_interp.h?h=release-2-7#n157.
Please consider including this information in the manual (https://www.gnu.org/software/gsl/doc/html/interp.html#c.gsl_interp_bsearch).
Thanks! -- Constantine
