+
+By default the program prints only titles of the found book. With one
+option `-v` it also prints database id, the list of authors and genres,
+and also series the book belongs to (if any) and the serial number of
+the book in the series. With two options `-v` (`-v -v` or simply `-vv`)
+it also prints the file date and language. With three `-v` it prints
+archive name, file name, extension and size, and flag if the book is
+marked to be deleted.
+
+Option `-P` provides the path to the directory with the library
+archives. By default the path is extracted from configuration file,
+section `[library]`, key `path`::
+
+ [library]
+ path = /var/lib/archives
+
+The option is useful for multiple databases (global option `-D`).
+
+Option `--get` allows to download a book from the library to a local
+file. The option allows to download exactly one book. The simplest way
+to use it is via option `--id`. The file is downloaded into the current
+directory with the name from the library.
+
+Configuration key
+
+| [download]
+| format = %a/%s/%n %t
+
+allows to set format for the download file pathname. Default format is
+`%f`, i.e. just filename. Other format specifiers are::
+
+ %a - author (one of if many)
+ %e - file extension
+ %f - file name in archive
+ %G - genre (one of if many), name
+ %g - genre (one of if many), title
+ %l - language
+ %n - series number (or 0)
+ %s - series
+ %t - title
+
+Format must not end in directory separator (`/` or `\\`). If specifier
+`%e` (extension) is not found in the format it is appended
+unconditionally with a dot. That is, format `%f` is equivalent to
+`%f.%e`.
+
+Option `-F|--format format` allows to overwrite this configuration value.
+
+Option `--get-many N` allows to download many books (at most N, where N
+is an integer). Options `--get-many N` and `--get` are, of course,
+mutually incompatible.
