Subject: [PATCH] libid3tag: move pkgconfig file into the nix-expression
 directory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[Bjørn Forsman:
 * use "mkdir -p" instead of "ensureDir" (deprecated)
 * place *.pc file in $out/lib/pkgconfig/ (instead of
   $out/share/pkgconfig/ which doesn't work)
 * prefix commit message with "libid3tag:"
]
