Overview

Imports a existing file which specified by the argument as a note.

A timestamp is generated referring to the birthtime of the given file. If birthtime is not available on the system, uses mtime (modification time).

When the option, “-m” (or “–use-mtime”) is specified, uses mtime instead of birthtime.

Occasionally, there is another note which has the same timestmap in the repository. Then, tries to create a new timestamp with a suffix. Unluckily, when such timestamp with a suffix already exists, tries to create a new one with increasing suffix. Suffix will be “001”, “002”, …, or “999”. In worst case, all suffix might have been already used. Then, abandons to import.
