# Script Name: bundle


# SYNOPSIS #
#   bundle [-s src_folder] [-d dest_folder] [-w]

# DESCRIPTION
#   bundle is a Bash script that monitors a source folder for changes and performs
#   synchronization tasks based on file types. It can compile SCSS and Pug files, and rsync
#   all other files to a destination folder. This script offers flexibility through command-line
#   options to customize source and destination folders, and to enable watch mode for continuous
#   monitoring.

# OPTIONS
#   -s, --src src_folder
#       Specify the source folder to monitor. The default is "src."
#
#   -d, --dest dest_folder
#       Specify the destination folder for synchronization. The default is "dist."
#
#   -w, --watch
#       Enable watch mode, which continuously monitors the source folder for changes. When a change
#       occurs, the script automatically compiles SCSS and Pug files and rsyncs other files to
#       the destination folder.

# USAGE
#   To use the script with default settings and enable watch mode:
#   $ bundle -w
#
#   To specify custom source and destination folders:
#   $ bundle -s custom_src_folder -d custom_dest_folder -w
#
#   To perform a one-time compilation and rsync without watch mode:
#   $ bundle-s custom_src_folder -d custom_dest_folder
