+Option `-p` provides the path to the directory with the library
+archives. By default the path is extracted from `m_librarian.conf`,
+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 `--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.
