Mansplain.exe is a program for fetching and maintaining help files. It is similar to the Linux man command or Get-Help in Windows PowerShell. Mansplain.exe is not meant to exclusively hold information about programs so go ahead and write files for whatever you like! Mansplain.exe also wraps the standard PowerShell Get-Help so it will return help files for PowerShell Cmdlets as well.
First see Installing mansplain.exe. Then just run
mansplain.exe sometopic -update to update a specific file or
mansplain.exe all -update to update all files.
-np to skip PowerShell and only check mansplain.exe files.
Maybe. Try it with Wine or something.
