# The new GDB commands:
# are entirely non instrumental
# do not depend on any "inline"(s) - e.g. size(), [], etc
# are extremely tolerant to debugger settings
#
# This file should be "included" in .gdbinit as following:
# source stl-views.gdb or just paste it into your .gdbinit file
#
# The following STL containers are currently supported:
#
# std::vector -- via pvector command
# std::list -- via plist command
# std::map -- via pmap command
# std::multimap -- via pmap command
# std::set -- via pset command
# std::multiset -- via pset command
# std::deque -- via pdequeue command

# std::queue -- via pqueue command
# std::priority_queue -- via ppqueue command
# std::bitset -- via pbitset command
# std::string -- via pstring command
# std::widestring -- via pwstring command
