Make a manifest file for Aspera.

#!/usr/bin/env bash
# make_aspera_manifest.sh

#
# Make a manifest file suitable for Aspera.
#
# Example
# -------
#
# Suppose we wish to send a folder full of files called "data". We want
# to maintain the directory structure of our files inside "data".
#
#        tree /path/to/data
#        /path/to/data
#        |-- file1.txt
#        |-- file2.txt
#        `-- folder1
#            `-- file3.txt
#        
#        1 directory, 3 files
#
# The manifest file should contain the full path to each file in the first
# column. The second column should contain the partial path, omitting
# directories that are specific to the machine you are using.
#
# Invoke this script like so:
#
#       ./make_aspera_manifest.sh /path/to/data /path/to/ > manifest.txt
#
# The resulting manifest.txt file will look like this:
#
#       /path/to/data/file1.txt	data/file1.txt
#       /path/to/data/file2.txt	data/file2.txt
#       /path/to/data/folder1/file3.txt	data/folder1/file3.txt
#
# Notice that the second column does not contain the string "/path/to/".
