<para>The hwdb files are read from the files located in the

All hwdb files are collectively sorted and processed in lexical order,
regardless of the directories in which they live. However, files with
identical filenames replace each other. Files in <filename>/etc</filename>

- over files with the same name in <filename>/usr/lib</filename>. This can be

disables the hwdb file entirely. hwdb files must have the extension
associated key-value pairs. Every record in the hwdb starts with one or
more match string, specifying a shell glob to compare the database
lookup string against. Multiple match lines are specified in additional
- consecutive lines. Every match line is compared indivdually, they are
+ consecutive lines. Every match line is compared individually, they are
combined by OR. Every match line must start at the first character of
the line.</para>
