update-default-ispell [--rebuild] [--ignore-symlinks]
This program is intended to be called from package postinst (with --rebuild), from select-default-ispell or from dictionaries-common postinst (with --ignore-symlinks).
Reads the system default from the debconf database and set default links in /etc/dictionaries-common pointing to the appropriate files in /usr/lib/ispell/. Also updates the system-wide setting /etc/dictionaries-common/ispell-default. If option --rebuild is given, rebuilds the /var/cache/dictionaries-common/ispell.db and the emacsen, jed, and SquirrelMail support (to be put in /var/cache/dictionaries-common/) from the files in /var/lib/dictionaries-common/ispell
