It's usually a good idea to leave your originals untouched if at all possible. I don't even like automatic renaming. I prefer to use originals as a template, and create new files. That way, if you find a bug in your program, it's 1) fix bug 2) try again instead of 1) restore from backup, 2) whoops what backup 3) fix bug, 4) try again.

to determine if two two doubles are equal, we check to see if
their absolute difference is very close to zero. . .if two numbers
are less than .00001 apart, theyre equal.

once the list is complete, ask the user to see if an element

GPODDER-BACKUP(1) User Commands GPODDER-BACKUP(1)
NAME
gpodder-backup - Backup and restore utility for gPodder user data
SYNOPSIS
gpodder-backup [--create|--extract] <archive.gpo.tar.gz> [options] gpodder-backup --purge
DESCRIPTION
This utility can be used to create a dump of the current gPodder data (configuration files + downloads), optionally replacing the real con-
tents of the download folder with zero-byte files (for submitting your data to a bug report without having to transfer lots of data).
OPTIONS
--version
show program's version number and exit
-h, --help
show this help message and exit
-c <FILE>, --create=<FILE>
Create a new archive
-x <FILE>, --extract=<FILE>
Extract an existing archive
-f, --fake-downloads
Store downloads as zero-byte files in backup
-n, --no-covers
Do not include cover files in archive
-D <DIR>, --destination=<DIR>
Extract downloads in different folder
-P, --purge
Remove current data (can be combined with --extract)
USAGE FOR BUG REPORTING
This command is useful if you want to report a bug in gPodder:
gpodder-backup --create bug123.gpo.tar.gz --fake-downloads
Backup your current data to file bug123.gpo.tar.gz, but don't store download data (create zero-size dummy files instead). You can
then attach bug123.gpo.tar.gz to the bug report.
If you are instructed to try gPodder from a "clean state", you can use the following command (be sure to backup your data before!):
gpodder-backup --purge
Remove all gPodder data, so you can start from a clean state
EXAMPLES
gpodder-backup --create today.gpo.tar.gz
Backup your current data to file today.gpo.tar.gz
gpodder-backup --extract mybackup.gpo.tar.gz
Restore (without purging) the contents of mybackup.gpo.tar.gz
gpodder-backup --extract default.gpo.tar.gz --purge
Remove current data, then restore the contents of default.gpo.tar.gz
gpodder-backup --purge
Remove all gPodder data, so you can start from a clean state
EXTRACTING FAKED DOWNLOADS
Please note that any existing downloads will be overwritten with zero-byte files when using the --extract option of the gpodder-backup
utility with a backup created with --fake-downloads
