Subject: Add compatibility for old File::Libmagic
X-Git-Tag: v0.2
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=ae4c0a94384ffc555c650a4021052235c537d560;p=pdfstitch

Add compatibility for old File::Libmagic

This allows pdfstitch to run on e.g. Debian Jessie where File::Libmagic
is older than 1.06.
