Subject svn commit: r1733370 - in /sis/branches/JDK8: application/sis-console/src/main/artifact/bin/ application/sis-console/src/main/artifact/conf/ application/sis-console/src/main/artifact/data/ application/sis-console/src/main/artifact/lib/ application/sis-...
Date Wed, 02 Mar 2016 21:23:43 GMT
Author: desruisseaux
Date: Wed Mar  2 21:23:42 2016
New Revision: 1733370

URL: http://svn.apache.org/viewvc?rev=1733370&view=rev
Log:
Improvement on the command-line tools:
- If there is more than one CRS in a WKT file, parse all of them.
- Report warnings emitted by the WKT parser.
- If the SIS_DATA environment variable is not set, use the <installation directory>/data
directory.
- Adjustments in the logging colors for making more visible when a log message spans many
lines.
