Leo is a simple backup program. It creates tar(1) files from a
pre-defined list. It can encrypt/sign files with gpg2(1).

═══════════════
I use this to quickly backup some of my files. It works on profiles,
profiles are simple lists of files which get backed up.
2.1 Profile
───────────
Profile is a simple hash table (`%profile') which contains the list of
profiles. The profiles are mapped to a list of file paths relative to
`$HOME' which are to be backed up.
You can run `help' to see all the profiles along with the paths.
Creating profiles is not required anymore, you can pass it any file in
current directory & it'll create a temporary profile.
2.2 Options
───────────
Some options can also be passed through environment variables. That
allows for configuration in shell rc file & the user can run leo
directly without looking at options.
━━━━━━━━━━━━━━━━━━━━━━━━
encrypt `LEO_ENCRYPT'
sign `LEO_SIGN'
delete `LEO_DELETE'
━━━━━━━━━━━━━━━━━━━━━━━━
2.2.1 encrypt/sign
╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌╌
`encrypt_sign' handles `gpg2' related functions. It passes `--yes' by
default.
*Note*: `gpg2' might compress the backups depending on your config.
Default is to enable compression, if you don't want this then add `-z
0' to `@options'. `-z' specifies the compression level & 0 means no
compression.
2.2.2 delete
╌╌╌╌╌╌╌╌╌╌╌╌
Removes the tar file after running gpg2(1). This means that either
`encrypt' or `sign' option must be passed.
2.2.3 help
╌╌╌╌╌╌╌╌╌╌
Running just `leo' will print help.
3 Example
═════════
┌────
│ # This will encrypt, sign & also delete the tar file for documents,
│ # journal, pass & ssh profile.
│ leo --encrypt --sign --delete documents journal pass ssh
│
│ # This will do the same. You can add these environment variables to
│ # your shell rc & then just run ``leo documents journal ssh pass'' to
│ # do the same.
│ LEO_ENCRYPT=1 LEO_SIGN=1 LEO_DELETE=1 leo documents journal ssh pass
│
│ # Backup this specific file.
│ cd $HOME/documents; leo --encrypt --sign andinus.org.gpg

══════
It's very easy to setup `leo', I made a demo video to show this. I
already have Perl environment setup for this.
*Note*: It's even more easy now, you don't have to create profiles
anymore.

You can also download the [cast file] directly & play it with
`asciinema'.

5 History
═════════
This was Leo's initial description:
Leo is a program to run my personal scripts. You might not
find them useful, these were previously shell scripts that
I rewrote in Perl.
I had created a sync function initially & was going to expand it. Then
I decided to remove those sync functions because it was too complex, I
replaced then with simple `sh' scripts.
I added a simple `archive' function later & decided to turn Leo into
that function. So, it's not a meta-program anymore. I was thinking of
creating something that does all the things for me but that'll be too
complex.
Later on the same day I removed dispatch table & switched to using
simple hash of lists to store backup paths mapped to profiles. And
also changed the word "archive" to "backup" everywhere.
I added a simple INI based config file before 0.1.0 release.
