  NAME
     extract_app_version.sh - A script to fetch and format app version details from a Gradle file.

  SYNOPSIS
     extract_app_version.sh

  DESCRIPTION
     This bash script is used to fetch the application version details from a Gradle properties file named "version-properties.gradle".
     It looks for the line with "appVersion" and extracts the version information, including major, minor, hotfix versions and build number.
     The script then exports an environment variable that represents the release branch name in a specific format.

  OPTIONS
     This script does not accept any command line options.

  EXAMPLES
     Running the script without any options:
         ./extract_app_version.sh

  NOTES
     This scripts makes use of several Unix/Linux commands such as grep, sed, awk. Make sure these utilities are installed on your system.
     The script expects that a file named "version-properties.gradle" is present in the same directory where this script is run."
  exit 1 # Exit after displaying man page.
