Inconsistencies:
Library cannot be specified for each argument.
Item cannot be specified for each sha1 checksum argument.
Version cannot be specified with -V Version.
Ambiguities:
Relative Unix path without '.' or '/' looks like Item or Version.
Main node Version without '.' looks like Item.
Idea #1:
The syntax [Library]:Item would help.
One should also be able to alias Library to a local nickname.
In fact, enforcing ':' in all dim namespace specifications really help.
:Item, :Version, :Item-Version would discriminate from Unix pathname.
This convention would add a new (but decent) restriction:
Relative Unix path containing ':' but no '/' would have to be prefixed
with './'.
Note:
getopts(3) also demands '--' or './' prefixing for Unix path starting
with '-' or '+'.
Idea #2:
:[Item]-Version would discriminate Item from Version, Version from flag.
:a # Item
:a1 # Item
:-a # Version (assuming the last digit constraint has been lifted)
:-a1 # Version
:+1 # Version
-a # flag
-a1 # flags (-a -1)
+1 # flag
a # Relative pathname
a1 # Relative pathname
1 # Relative pathname
This convention would ease the integration with other tools
(expecting standard Unix flag and pathname conventions).
Suppressing ambiguities would also simplify argument parsing.
