'''Plug-in originally written by cube. Tweaked, compiled and uploaded by KiCHiK'''

== Description ==
This plug-in will return every available CD-ROM drive on the user's machine one by one.

This plug-in requires NSIS 2.

Put EnumCDs.dll in the Plugins directory under the directory where you installed NSIS.

== How To Use ==
To use it call EnumCDs::next with the /NOUNLOAD flag, and keep popping the
results, the CD-ROM drive letters, one by one until the plug-in pushes "done".
Then call EnumCDs::next once more without the /NOUNLOAD flag, pop the
second "done" and you're done.

== Example ==
<highlight-nsis>
again:
  EnumCDs::next /NOUNLOAD
  Pop $0
  StrCmp $0 "error" done
  DetailPrint $0
StrCmp $0 "done" done again
done:
  EnumCDs::next
  Pop $0
</highlight-nsis>

== System plug-in alternative ==
<highlight-nsis>
!include LogicLib.nsh
!define /IfNDef DRIVE_CDROM 5
