# This script tests debugging information generated by a compiler.

# - Input source program. Usually this source file is decorated using
# special comments to communicate debugger commands.
# - Executable file. This file is generated by the compiler.
#
# This perl script extracts debugger commands from input source program
# comments in a script. A debugger is used to load the executable file
# and run the script generated from source program comments. Finally,
# the debugger output is checked, using FileCheck, to validate
# debugging information.
