Return to bsd.pkg.debug.mk CVS log

Up to [cvs.NetBSD.org] / pkgsrc / mk

One ident string per file is enough.

Committed although we are in a freeze, since it doesn't affect building the
packages.

# $NetBSD: bsd.pkg.debug.mk,v 1.20 2007/09/27 12:49:14 rillig Exp $
#
# Public targets:
#
# debug:
#	outputs the values of some commonly used variables and the
#	contents of some files which are useful for tracking bugs,
#	especially for packages that use the GNU autotools.
#

PRINTF?=	printf

# Note: In the many cases where ${x} is used, the quoting is left out
# intentionally, since x is an element of a list of shell words, and
# passing such a shell word to the shell should still result in one
# word. That way, no extra level of quoting is introduced.
#
# The only exception is the "<" character in CONFIGURE_ARGS, where it
# is often used to redirect the input coming from another source. That
# character has to be quoted.
