S: supportedghcman.yaml is a local configuration file. ghcman searches it in the current directory and its parents recursively until $Env:USERPROFILE or the root. A user global configuration file is $Env:APPDATA\ghcman\config.yaml, and a system global one is $Env:ProgramData\ghcman\config.yaml.
This is a sample of ghcman.yaml and config.yaml.
ghc:
HEAD: somewhere\directory\which\contains\ghc
fix-some-issue: other\directory
cabal:
HEAD: somewhere\directory\which\contains\cabalWrite-GhcmanConfigTemplate function creates ghcman.yaml with the template.
When you want to check the loaded configuration, use Get-GhcmanConfig function.
You can set $Env:GhcmanInstall to specify a directory where GHCs and Cabals are installed. Its default is $Env:APPDATA\ghcman.
