 HELP="
 Build GTK4 or GTK3 bindings and (optionally) copy them to binary repository.
 Paramaters (specified in this order):
 clean    - delete *.o and *.so files from current folder. If this is the only paramater, do nothing else.
 			But if other paramaters are given and this is the first one, then continue with other actions.

 One of the following 3:
 -gtk3   : Build bindings with GTK3.
 -gtk4   : Build bindings with GTK4.
 -gtk-all : Build bindings with GTK3 as well as GTK4. Note, this flag triggers cleanups before each build
 			because a cleanup is required when building different GTK versions for linking to be done correctly.
 			During active development, if you only want to compile updated files, use -gtk3/-gtk4 flags instead,
 			however do not forget to do a cleanup in between gtk3/gtk4.

 install  - copy *.so libraries to binary repository.

 --print-outputdir-and-exit - This simply echos the OUTPUT folder where .so libs are copied to,
 							 then exits the script. Used by external

 -- Examples:
 Most commonly used:
 ./build.sh -gtk-all install
 This will clean everything in your repository, build GTK3 and GTK4, then copy .so files to binary repository.

 Also:
 ./build.sh     	  - only build .so files, do not copy them across. Build according to what GTK_VERSION is set to.
 ./build.sh clean  	  - clean working directory of *.o and *.so files.
 ./build.sh -gtk4 install	 - build.so files and copy to binary repository

 Also note:
 Sometimes you might have to cleanup the binary repository manually as old *.so files are not automatically removed
 by clean command. Navigate to binary repository and:
 git clean -xdf #If new files were added to repo.
 git reset --hard  #If existing binary was overwritten.
