#  Authors : D.Bertini and M.Ivanov
#  Date: 23/10/2000
#  Updated: 10/05/2001 D.Bertini, v2.0 port to gdb5.0 + glibc2.2
#
#
#  To activate the memory checker you have to set in the .rootrc file
#  the resource Root.MemCheck to 1 (e.g.: Root.MemCheck: 1) and you
#  have to link with libNew.so (e.g. use root-config --new --libs) or
#  use rootn.exe. When all this is the case you will find at the end
#  of the program execution a file "memcheck.out" in the directory
#  where you started your ROOT program. Alternatively you can set
#  the resource Root.MemCheckFile to the name of a file to which
#  the leak information will be written. The contents of this
#  "memcheck.out" file can be analyzed and transformed into printable
#  text via the memprobe program (in $ROOTSYS/bin).
