# Globals
# A hash to count visited bugs, and also to avoid processing repeated bugs

# global only to avoid excessive complication in the recursion invocation

# DumpKids recurses through the bug hierarchy starting at bug i, and
# appends the bug information found to the html global variable. The
# parameters are not straightforward, so look at the examples.

# DumpKids(i, target [, depth])
#
# Params
# i: The bug id to analyze
# target: The type we are looking for; either "blocked" or "dependson"
# Optional
# depth: The current dependency depth we are analyzing, used during
# recursion
# Globals Modified
# html: Bug descriptions are appended here
# realdepth: We set the maximum depth of recursion reached
# seen: We store the bugs analyzed so far
# Globals Referenced
# maxdepth

#
# Examples:
# DumpKids(163, "blocked");
# will look for bugs that depend on bug 163
# DumpKids(163, "dependson");
# will look for bugs on which bug 163 depends
