General improvements

[dmotte]

In short, I have made the following changes:

• improved README and structure
• added useful --help message to the command
• improved readability and usability in general
• removed OS strict check, because this script may also work on other OSes. For example i tested it on Windows with Git Bash and it works

This also resolves #5

Hello,
Thanks for the work done.
I will look at your changes.

@dmotte on Windows with Git Bash, is the uname command exist ? what is the value return by this uname command ?

[dmotte]

@tst2005 this is the output of both uname and uname -a. As you can see, it's not really useful 😅

Motte@dmottepc MINGW64 ~
$ uname
MINGW64_NT-10.0-17763

Motte@dmottepc MINGW64 ~
$ uname -a
MINGW64_NT-10.0-17763 dmottepc 3.1.7-340.x86_64 2020-10-23 13:08 UTC x86_64 Msys

Despite of you tell, It is usefull. I see Windows with Git Bash use the well known mingw-w64 to compile their stuff.
Then I added a MINGW64* support.

I will continue soon to update the README about Installation. It need to be improved but i'm not sure to follow what you wrote.

I will keep the verbose option (that you had dropped).
I will keep git-timesync into the bin/directory.
For the rest, I think I apply changes close to your PR (drop --force, add help, etc.).

[dmotte]

Thanks for your time. Yeah i know the thing about MINGW64, but i would prefer if there is no check at all and the script assumes to work on all OSes where Bash works... but that's subjective.
Anyway, if you really want to perform that check, i advise you to check for MINGW* instead, so the script will work even on MINGW32 (32-bit) systems.

[tst2005]

I understand but it is new, I suppose there will be some differences.
After some time, if there is no difference/issue, I will merge them with pleasure!

To be honest I didn't target Bash (even it is most used) but any POSIX shell.
I'm trying to be able to run git-timesync on any unix.

I just realize, I included some part of your work outside of a PR, then it is added like I did it. Sorry for that.

[dmotte]

No problem for that. It's your project so feel free to do what you want 😉

Hello @dmotte
Your README changes seems nice, I will include them ASAP.
I re-opened your issue about WSL support, I need something to detect properly the WSL case.
