	Use:   "build",
	Short: "Build standalone, portable webapp from Calibre library.",

library including all the metadata needed. It creates BROWSE_LIBRARY.html in
root directory of the local Calibre library. For search (authors, titles,
tags...) it uses rendered metadata from static/data{1-8}.js files.

Every time the directory path and/or librarian is provided it is saved in
the configuration file for the future use (therefore: 'accorder build PROFILE'
should be enough for the next successful build).`,
