dnl slurp-ffmpeg.m4 0.1.1
dnl a macro to slurp in ffmpeg's cvs source inside a project tree
dnl taken from Autostar Sandbox, http://autostars.sourceforge.net/
dnl Usage:
dnl AS_SLURP_FFMPEG(DIRECTORY, DATE, [ACTION-IF-WORKED [, ACTION-IF-NOT-WORKED]]])
dnl
dnl Example:
dnl AM_PATH_FFMPEG(lib/ffmpeg, 2002-12-14 12:00 GMT)
dnl
dnl make sure you have a Tag file in the dir where you check out that
dnl is the Tag of CVS you want to have checked out
dnl it should correspond to the DATE argument you supply, ie resolve to
dnl the same date
dnl (in an ideal world, cvs would understand it's own Tag file format as
dnl a date spec)
AC_DEFUN([AS_SLURP_FFMPEG],

FAILED=""
DIRECTORY=`pwd`
# get/update cvs
if test ! -d $1; then mkdir -p $1; fi
dnl we need to check $srcdir/$1 or it will always checkout ffmpeg even if it is there
dnl at least when top_srcdir != top_builddir.
dnl FIXME: unfortunately this makes the checkout go into top_srcdir
cd $srcdir/$1
