Select-Plugins.ps1

# Select-Plugins.ps1

# selectively enable / disable vCheck Plugins

# presents a list of plugins whose names match *.ps1 or *.ps1.disabled
# 
# disabled plugins will be renamed as appropriate to <pluginname>.ps1.disabled
# enabled plugins will be renamed as appropriate to <plugin name>.ps1

# To use, run from the vCheck directory
#     or, if you wish to be perverse, copy to the plugins directory and rename to 
#         "ZZ Select Plugins for Next Run.ps1" and run vCheck as normal.

# Great for testing plugins.  When done, untick it...

# If run as a plugin, it will affect the next vCheck run, not the current one,
#   as vCheck has already collected its list of plugins when it is invoked
#   so make it the very last plugin executed to avoid counter-intuitive behaviour

# based on code from Select-GraphicalFilteredObject.ps1 in
#  "Windows Powershell Cookbook" by Lee Holmes.
