; Inno Setup script for Ebbe's Meme Clipboard.
;
; Build with:
;   "%LocalAppData%\Programs\Inno Setup 6\ISCC.exe" installer\EbbesMemeClipboard.iss
;
; Expects an installer-flavoured publish first (note: compression DISABLED on purpose):
;   dotnet publish src\EbbesMemeClipboard\EbbesMemeClipboard.csproj -c Release -r win-x64 ^
;     --self-contained true -p:PublishSingleFile=true ^
;     -p:IncludeNativeLibrariesForSelfExtract=true -p:EnableCompressionInSingleFile=false ^
;     -o publish-installer
;
; Leaving .NET's own single-file compression off lets Inno's LZMA2 compress the raw bytes
; instead, which it does far better: ~51 MB setup vs ~70 MB when double-compressing. The
; installed exe is larger on disk (172 MB vs 75 MB) but starts faster, since there's no
; decompression on launch. The separate publish\ folder keeps the compressed build for
; anyone who just wants the portable single exe.
