# Creates an action that aggregates vector icon files (.icon) into a C++ file.
# In addition to running the action, the outputs should be added to another
# target's sources for compilation.
#
# Parameters
#
# sources (required)
# A list of icon filenames to use as inputs.
#
# icon_directory (required)
# The path component of the location of the icons, relative to the current
# directory. For example, if the invoking BUILD file exists in //foo/bar
# and the icons are in //foo/bar/vector_icons/, then icon_directory should
# be set to "vector_icons". There must also be template files in this
# directory.
#
# Example
#
# See BUILD.gn in this directory (//components/vector_icons/) for an example.
