Reads zettel data from a file (or from standard input / stdin) and renders it to standard output / stdout. This allows Zettelstore to render files manually. ``` zettelstore file [-t FORMAT] [file-1 [file-2]] ``` ; ''-t FORMAT'' : Specifies the output format. Supported values are: [[''html''|00001012920510]] (default), [[''md''|00001012920513]], [[''shtml''|00001012920525]], [[''sz''|00001012920516]], [[''text''|00001012920519]], and [[''zmk''|00001012920522]]. ; ''file-1'' : Specifies the file name, where at least metadata is read. If ''file-2'' is not given, the zettel content is also read from here. ; ''file-2'' : File name where the zettel content is stored. If neither ''file-1'' nor ''file-2'' are given, metadata and zettel content are read from standard input / stdin.
