Note on Resolve-Path:
All paths are sent through Resolve-Path/Resolve-PSFPath in order to convert them to the correct path separator.
This allows ignoring path separators throughout the import sequence, which could otherwise cause trouble depending on OS.
Resolve-Path can only be used for paths that already exist, Resolve-PSFPath can accept that the last leaf my not exist.
This is important when testing for paths.

This is an example configuration file
 
By default, it is enough to have a single one of them,
however if you have enough configuration settings to justify having multiple copies of it,
feel totally free to split them into multiple files.

# Example Configuration
Set-PSFConfig -Module 'MigrateCitrixUPMtoFSLogix' -Name 'Example.Setting' -Value 10 -Initialize -Validation 'integer' -Handler { } -Description "Example configuration setting. Your module can then use the setting using 'Get-PSFConfigValue'"
#>


Set-PSFConfig -Module 'MigrateCitrixUPMtoFSLogix' -Name 'Import.DoDotSource' -Value $false -Initialize -Validation 'bool' -Description "Whether the module files should be dotsourced on import. By default, the files of this module are read as string value and invoked, which is faster but worse on debugging."
Set-PSFConfig -Module 'MigrateCitrixUPMtoFSLogix' -Name 'Import.IndividualFiles' -Value $false -Initialize -Validation 'bool' -Description "Whether the module files should be imported individually. During the module build, all module code is compiled into few files, which are imported instead by default. Loading the compiled versions is faster, using the individual files is easier for debugging and testing out adjustments."

<#
Stored scriptblocks are available in [PsfValidateScript()] attributes.
This makes it easier to centrally provide the same scriptblock multiple times,
without having to maintain it in separate locations.
 
It also prevents lengthy validation scriptblocks from making your parameter block
hard to read.
 
Set-PSFScriptblock -Name 'MigrateCitrixUPMtoFSLogix.ScriptBlockName' -Scriptblock {
