Meta-script that generates a script to apply patches in bulk

generate_patching_script_for_folder_structured_patches.sh

#Generates script to apply patches from folder structure 
#For example if you have the following structure:
#  ~/patch/A/subA/*.patch , and patches which have subA as "patch root",
#  meaning they should be applied like this: "cd subA ; patch -p1 < *.patch"
#  then this script generates a script with commands that will do exactly then in bulk.
#
# Sample script output:
#	echo "Entering directory: $PWD"
#	echo "Applying 0001-Fix-in-handling-header-decode-errors.bulletin.patch"
#	cd ./external/libmpeg2
#	patch -p1 < /home/kushtrim/Desktop/patches/platform/external/libmpeg2/0001-Fix-in-handling-header-decode-errors.bulletin.patch
#	cd - > /dev/null
#	echo "---------------------------------"
