# ./floatsign source "iPhone Distribution: Name" -p "path/to/profile" [-d "display name"]  [-e entitlements] [-k keychain] [-b "BundleIdentifier"] outputIpa
#
#
# Modifed 26th January 2012
#
# new features January 2012:
# 1. change the app display name
#
# new features April 2013
# 1. specify the target bundleId on the command line
# 2. correctly handles entitlements for keychain-enabled resigning
#
# new features November 2014
# 1. now re-signs embedded iOS frameworks, if present, prior to re-signing the application itself
# 2. extracts the team-identifier from provisioning profile and uses it to update previous entitlements
# 3. fixed bug in packaging if -e flag is used
# 4. renamed 'temp' directory and made it a variable so it can be easily modified
# 5. various code formatting and logging adjustments
#
# new features October 2015
# 1. now re-signs nested applications and app extensions, if present, prior to re-signing the application itself
# 2. enables the -p option to be used more than once
# 3. ensures the provisioning profile's bundle-identifier matches the app's bundle identifier
# 4. extracts the entitlements from the provisioning profile
# 5. copy the entitlements as archived-expanded-entitlements.xcent inside the app bundle (because Xcode does too)
#
