Comment (by mmetz):
Replying to [ticket:2540 rouault]:
> The attached patch adds 2 new options flags:
> -r : Do not write COLOR_TABLE_RULES_xxxx metadata item. (The 'r' is the
one of rules)
> -g : Do not write Generated_with metadata item
>
> Those metadata items are fairly GRASS specific and do not make sense for
most users of rasters generated with r.out.gdal, potentially leading to
confusion or compatiblity problems
There is a new flag 'm' to enhance compatibility with regard to metadata.
If the flag is set, GRASS color rules are not written to metadata, and the
"Generated_with" metadata key has been replaced with TIFFTAG_SOFTWARE for
GTiff (one of the baseline TIFF tags).
Some software expects a nodata value in the metadata, even if there are no
nodata in a band. If a nodata value is given with the nodata option, it
is now always written to metadata. Implemented in r69128-30 for relbr70,
relbr72, and trunk.
