*** 355,367 ****
  The DJGPP-built version from http://cscope.sourceforge.net is known to not
  work with Vim.
  
! There are a couple of hard-coded limitations:
! 
!     1. The maximum number of cscope connections allowed is 8.  Do you
!     really need more?
! 
!     2. Doing a |:tjump| when |:cstag| searches the tag files is not
!     configurable (e.g., you can't do a tselect instead).
