Tag: bin-or-sbin-binary-requires-usr-lib-library
Description: This package ships a binary in /bin or /sbin that requires a
 library in /usr/lib.  This will make impossible to use this binary before /usr
 is mounted.

Tag: broken-symlink
Description: This package ships a symlink which points to a non-existent file.

Tag: incompatible-licenses
Description: Licenses of the libraries the binary is linked to are incompatible.

Tag: library-not-found
Description: The binary is linked with a library, which cannot be found.

Tag: missing-copyright-file
Description: The copyright file for this package is missing.  This often
 happens if /usr/share/doc/<pkg>/ was a real directory in a previous version of
 the package, but it's now a symlink; dpkg never replaces directory
 with a symlink to a directory.

 Debian Policy §12.5, §6.6

Tag: missing-symbol-version-information
Description: The binary uses versioned symbols, but the library provides only
 unversioned ones.

Tag: obsolete-conffile
Description: The current version of this package no longer ships a conffile
 (that used to be included in the past).  However, the conffile hasn't been
 removed on upgrade.

Tag: pyshared-file-not-bytecompiled
Description: This package ships Python modules in /usr/share/pyshared that are
 not byte-compiled.

Tag: symbol-size-mismatch
Description: The symbol has changed size since the package was built. It might
 be an indication that the library broke ABI.  If ABI wasn't broken, and the
 library bumped shlibs (or symbols), the package should be binNMUed.

Tag: undefined-symbol
Description: The symbol has not been found in the libraries linked with the
 binary.  Either the binary either needs to be linked with an additional
 shared library, or the dependency on the shared library package that provides
 this symbol is too weak.
