#  TestRunner.sh - This script is used to run arbitrary unit tests.  Unit
#  tests must contain the command used to run them in the input file, starting
#  immediately after a "RUN:" string.
#
#  This runner recognizes and replaces the following strings in the command:
#
#     %s - Replaced with the input name of the program, or the program to
#          execute, as appropriate.
#     %llvmgcc - llvm-gcc command
#     %llvmgxx - llvm-g++ command
#     %prcontext - prcontext.tcl script
#     %t1 - temporary file name (derived from testcase name)
#
