* Maintains and accesses a Xapian index of package descriptions.

* Contrarily to Debtags and Popcon, TextSearch does not attempt to create the
* index in the home directory if no system index is found and it is not
* running as root: this is to avoid secretly building large indexes (>50Mb)
* in the home directory of users.
*
* The idea then is to have root keep the index up to date, possibly running a
* reindexing tool once a day, or after an apt-get update.
*
* This works because the full text search index is useful even if it is
* slightly out of date.
