  "Create 'check.sh', a script suitable for use with hg bisect.

To use, first clone 

   hg clone https://evenson.not.org@code.google.com/p/abcl-dynamic-install/ ./abcl
   cd abcl

Then copy 'check.lisp' to this directory, as well as the bisect
wrapper script 'check.sh'.  Adjust 'check.lisp' to raise an error if
the problem exists in a given changeset.

Then reset the hg bisection data via:

   hg bisect --reset

Mark the last known good and earliest known bad changeset via

   hg bisect --good <revision>
   hg bisect --bad <revision>

Then issue

   hg bisect --command sh ./check.sh

which will churn through the revisions until it finds the earliest
known version in which the 'check.lisp' raises the error.
