annotate include/mb_redraw_man.h @ 186:530bb7728546 include_mb_test

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Move header files to $(top_srcdir)/include/ and prefixed with 'mb_'. This is the solution that I dicussed with FourDollars, last night.
