# mkflags.py generates .pri and .qrc files from Mumble's
# flag SVGs, such that the flags can be included as Qt
# resources.
#
# The script splits the flags into multiple .qrc files once
# a single .qrc file exceeds a given threshold.
#
# This is because older compilers (and old hardware, too!)
# can have problems with large source files. When Qt embeds
# a .qrc file, it generates a .cpp file and compiles it. Some
# of our flag SVGs can be quite large, and if we only use a
# single .qrc file, it is (as of this writing) 32MB+ large.
