/*
** WEBPAGE: sqlar
** WEBPAGE: zip
**
** Generate a ZIP or SQL archive for the check-in specified by the "r"
** query parameter.  Return the archive as the HTTP reply content.
**
** If the NAME contains one "/" then the part before the "/" is taken
** as the TAG and the part after the "/" becomes the true name.  Hence,
** the following URLs are all equivalent:
**
**     /sqlar/508c42a6398f8/download.sqlar
**     /sqlar?r=508c42a6398f8&name=download.sqlar
**     /sqlar/download.sqlar?r=508c42a6398f8
**     /sqlar?name=508c42a6398f8/download.sqlar
**
** Query parameters:
**
**   name=NAME           The base name of the output file.  The default
**                       value is a configuration parameter in the project
**                       settings.  A prefix of the name, omitting the
**                       extension, is used as the top-most directory name.
