Support for multiple value for an option

[gogito]

Hi, the script is great already but it would be completed if it can support multiple value for an option when working would multiple input file for example:

myscript --file file1 file2 file3

Right now it doesn't seem like there is a way to do this if I'm understanding correctly.

Hi

Its syntax cannot distinguish between the following two

myscript --file file1 file2 file3
myscript --name value file1 file2

There is no specification for multiple-valued options in either POSIX or GNU. If necessary, use the following alternative way.

myscript file1 file2 file3
myscript --file file1,file2,file3
myscript --file file1 --file file2 --file file3

Guideline 8:
When multiple option-arguments are specified to follow a single option, they should be presented as a single argument, using <comma> characters within that argument or characters within that argument to separate them.
