iOS automatic version script
#!/bin/sh
###
# Version: $Major.$Minor.$Commit
#
# How it works:
# 1. To roll minor number, tag each App Store release with a message.
# 2. To roll major number, create an additional tag on the last App Store
# release (e.g. "2.17.9") with new major number (e.g. "3").
# 3. `Release` builds require a clean working directory.
# 4. Non-`Release` builds have a commit number of '0'.
#
# Where it goes:
# 1. Pass no arguments to write to the target's derived Info.plist
# 2. Pass 'print marketing' or 'print build' to echo that version number to stdout
# 3. Pass 'pch' to write to a project-level PCH file for Info.plist preprocessing
###

marketing=`echo $build | awk '{split($0,v,"."); print v[1] "." v[2]}'`

status() { >&2 echo $1; }
