# Import the module that defines complex Gecko debugging commands.  This assumes
# you are either running lldb from the top level source directory, the objdir,
# or the dist/bin directory.  (.lldbinit files in the objdir and dist/bin set
# topsrcdir appropriately.)

# single compiled file breaks lldb breakpoint setting. This works around that.
