cp_xresources

#!/bin/python3

#copies colors from xresources to various config files
#
#to use, copy the config file in question, add .in extension, and add the path
#(without .in extension) to targets list below. The script will copy the .in file
#to the real config path and replace all codes with their corresponding colors
#
#codes are in the following format:
# %cl[!r]NAME%
#for numbered colors, the name is just the number, for foreground and background
#it is abreviated to fg and bg, and for anything else it is the same as whatever
#you set it to in the xresources file.
#
#add the !r if you want the output to be comma separated rgb format, otherwise it
#will be hexadecimal
