Usage: depcomp [--help] [--version] PROGRAM [ARGS]
39
Run PROGRAMS ARGS to compile a file, generating dependencies
42
Environment variables:
43
depmode Dependency tracking mode.
44
source Source file read by `PROGRAMS ARGS'.
45
object Object file output by `PROGRAMS ARGS'.
46
depfile Dependency file to output.
47
tmpdepfile Temporary file to use when outputing dependencies.
48
libtool Whether libtool is used (yes/no).
50
Report bugs to <bug-automake@gnu.org>.
