X-Git-Tag: YAZ.3.0.20~27
X-Git-Url: http://jsfdemo.indexdata.com/cgi-bin?a=commitdiff_plain;h=22a9064b93713ca401a98cf7f416407c60b19def;p=yaz-moved-to-github.git

Improved tokenization for yaz-client coammnds update and xmles.

The yaz-client commands update and xmles takes documents as parameters
and parse_cmd_doc is used. This now accepts one of the forms:
 <filename, "quoted string", straightstring .
