# 1.) Copies lyx-files to another location
# 2.) While copying,
#   2a.) searches for relative references to files and
#        replaces them with absolute ones
#   2b.) In order to be able to compile with luatex or xetex
#        changes default fonts to use non-tex-fonts instead
#
# Syntax: perl useSystemFonts.pl sourceFile destFile format
# Each param represents a path to a file
# sourceFile: full path to a lyx file
# destFile: destination path
#   Each subdocument will be copied into a subdirectory of dirname(destFile)
# format: any string of the form '[a-zA-Z0-9]+', e.g. pdf5
