# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in. You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':'.

valgrind: valgrind
valgrind:
valgrind: Valgrind is a tool to help finding memory-management problems in
valgrind: programs. When a program is run under Valgrind's supervision, all
valgrind: reads and writes of memory are checked, and calls to 'malloc', 'new',
valgrind: 'free' and 'delete' are intercepted. As a result, Valgrind can detect
valgrind: a lot of problems that are otherwise very hard to find.
