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)
|
|

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.
