PowerShell template profile: adds some useful aliases and functions
### PowerShell template profile
### Version 1.03 - Tim Sneath <tim@sneath.org>
### From https://gist.github.com/timsneath/19867b12eee7fd5af2ba
###
### This file should be stored in $PROFILE.CurrentUserAllHosts
### If $PROFILE.CurrentUserAllHosts doesn't exist, you can make one with the following:
### PS> New-Item $PROFILE.CurrentUserAllHosts -ItemType File -Force
### This will create the file and the containing subdirectory if it doesn't already
###
### As a reminder, to enable unsigned script execution of local scripts on client Windows,
### you need to run this line (or similar) from an elevated PowerShell prompt:
### Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
### This is the default policy on Windows Server 2012 R2 and above for server Windows. For
### more information about execution policies, run Get-Help about_Execution_Policies.

Really like the bash like $ - is there any way I can get it to stick when using a .bat file to build a Jekyll site?
