10 # Find a program when cross-compiling, or use a default when not.
11 # RESULT = variable which records the outcome
12 # CROSS_PROG = program to look for when cross-compiling
13 # NORMAL_PROG = program to use when not cross-compiling
14 # Example: KPSE_CROSS_PATH_PROG([TANGLE], [tangle], [./tangle]) sets
15 # 'TANGLE' to the program 'tangle' found in PATH when cross-compiling,
16 # and to './tangle' if not.
