-====== Patching - Creating a patch ======
-If you are a developer you might come across bugs that you fixed yourself.  To share the fix with others you can use the command diff which scans two files and lists the differences.  If you output this into a file e.g. differences.patch the users can use your file as the input for the command patch.
-===== Creating the patch file =====
-<code bash>
-# Run diff to get all the differences of two entities. These can be files but also folders.
-# The result is piped into
-#   c => output NUM (default 3) lines of copied context
-#   r => recursive
-#   B => ignore changes whose lines are all blank
-diff -crB Folder1 Folder2 > bugfix.patch
-</code>
-Copy the patch file into the directory of the file or folder you want to patch. If the patch was created of two folders change into the directory that should be patched and run the patch from there.  Thus the patch command knows what folder should be patched.
-===== Running the patch =====
-<code bash>
-# patching files
-patch –dry-run -p1 -i bugfix.patch # Patch simulation
-patch -p1 -i bugfix.patch          # Patch in action
-# patching folders
-cd folder_to_be_patched
-patch –dry-run -p1 -i ../bugfix.patch # Patch simulation
-patch -p1 -i ../bugfix.patch          # Patch in action
