Replace all local images references in HTML with base64 inline data, e.g. for HTML emails
#!/bin/bash
# Searches for <img src="localImage" alt="altText"/> in index.html and replaces with:
# <img src="data:image/png;base64,..." alt="altText"/>
# writes output to build/index.html
mkdir -p build
# awk is really awkward: does not accept regexp groups :(
# I'll keep the () anyways for my mental health!

iOS/sh: Extract sub-libraries from a given library without access to source code to avoid namespace clashes
#!/bin/zsh
# We at WeltN24 were facing the problem that two libraries that we integrated
# in our iOS project, used the same sub-library which resulted in naming
# conflicts due to the non-existing namespaces in Swift.
#
# If you know what you are doing you can try to solve this conflict by
# extracting the shared sub-library from one of the libraries you want to
# integrate. You can even do this if you don't have access to the source code
# using the lipo (create or operate on universal files) and ar (create and
