No module named 'ConfigParser': only help functions are implemented, for the sake of help2man Usage: axi-cache [options] command [args] Query the Apt Xapian index. Commands: search commands: axi-cache again [query] repeat the last search, possibly adding query terms axi-cache help show a summary of commands axi-cache info print information about the apt-xapian-index environment axi-cache last [count] show the last results again axi-cache more [count] show more terms from the last search axi-cache rdetails pkgname[s] show details of reverse relationships for the given packages axi-cache search [terms] start a new search apt-cache front-ends: axi-cache depends pkgname[s] run apt-cache depends pkgname[s] axi-cache madison pkgname[s] run apt-cache madison pkgname[s] axi-cache policy pkgname[s] run apt-cache policy pkgname[s] axi-cache rdepends pkgname[s] run apt-cache rdepends pkgname[s] axi-cache show pkgname[s] run apt-cache show pkgname[s] axi-cache showpkg pkgname[s] run apt-cache showpkg pkgname[s] axi-cache showsrc pkgname[s] run apt-cache showsrc pkgname[s] Options: --version show program's version number and exit -h, --help show this help message and exit -s SORT, --sort=SORT sort by the given value, as listed in /var/lib/apt- xapian-index/values. Add a '-' to reverse sort order --tags show matching tags, rather than packages --tabcomplete=TYPE suggest words for tab completion of the current command line (type is 'plain' or 'partial') --last use 'show --last' to limit tab completion to only the packages from the last search results --all disable pagination and always show all results. Note that search results are normally sorted by relevance, so you may find meaningless results at the end of the output
