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
DEPDIR directory where to store dependencies.
47
depfile Dependency file to output.
48
tmpdepfile Temporary file to use when outputing dependencies.
49
libtool Whether libtool is used (yes/no).
51
Report bugs to <bug-automake@gnu.org>.

298

300
