# In this directory, a number of different processes are managed:
#
# 1) PNG files are created from SVG files
# 2) CPP files are created from PNG files.
# 3) Object files are created from CPP files.

# Step 3) is universal and is done for any builder, whereas steps 1) and 2) are
# optional and depend on MAINTAIN_PNGS being defined in CMake.  The reason we
# can skip 1) and 2) is that the *.CPP files are part of the source tree so
# do not need to rebuilt by a typical builder.  However, because the *.CPP files
# are part of the source tree, and subject to version control, they should be built
# only when needed, otherwise this results in a diff for the version control system.
# Therefore steps 1) and 2) are driven by CMake (if MAINTAIN_PNGS) which gives
# us conditional *.CPP building based on an edit to the respective *.SVG file.

# If MAINTAIN_PNGS is not defined, then you are a normal builder and no special
# tools are required.  If MAINTAIN_PNG is defined, then you are a PNG maintainer
# and will need the following tools findable in your PATH:
#
# 1) imagemagick - all its programs must be on your PATH
# 2) inkscape - command line mode is used, must be on your PATH
# 3) pngcrush -
#

# lower case is used for local variables, uppercase for global variables


# If this file is used as part of the Kicad build, disable the stand alone build mode.
