# Provide support for easy porting of Electron applications that are distributed
# in binary form.
#
# Feature:	electronfix
# Usage:	USES=electronfix:version
#
# An example usage might be:
#         USES=   electronfix:24
#
# Variables, which can be set by the port:
#
#  ELECTRONFIX_SYMLINK_FILES	List of files to be symlinked from Electron distribution.
#
#  ELECTRONFIX_MAIN_EXECUTABLE	File name of the main executable to be replaced
#				with the original Electron binary.
