Make better parametrisation and help

[kpym]

Sorry to tell you but I'm struggling with the configuration of amber for different reasons :

• Some flag helps is too short and cryptic. Example: Enable .gitignore skip, do we enable to skip .gitignore and search for ignored files or we enable to skip the files that are in .gitignore?
• Not clear should we use parameter or it is default. Example: --key-from-file, should we specify a filename (in which case it is probably an option and not a flag) or should we use some default filename?
• The flag do not correspond to the variables in amr/s.toml. Example: --skip-gitignore is "disabled" by default and we "enable" it with this flag, but skip_gitignore in .toml is true ("enabled") by default. So it looks like that this two defaults are opposite to each other.
• It looks that we can only "enable" some flags, but what if they are enabled in the .toml config and we want to disable them by flag ? If this is possible (by putting for example =false ) this should be documented.
• Some variables in .toml are only valid for ambr but not for ambs and the documentation do not specify this. Example: interactive.

Suggestions about the .toml configs:

• Enable single .amber.toml with sections for ambs and ambr for the specific flags. Example:

skipped = true # valid for ambr and ambs
[ambr]
interactive = false # only for ambr
[ambs]
skip_gitignore = false  # only for ambs

• Look for .toml config files in multiple folders, for example (in order) :
  • the current path (like for .gitignore)
  • ~/.config/amber
  • ~/.config/
  • ~
