+ Fetches, verifies and installs the specified PACKS from the
+ manifest into the `STATIC-DIR/emoji/PACK-NAME`
+
+ ### Options
+
+ - `-m, --manifest PATH/URL` - same as ls-packs
+
+ ## gen-pack
+
+ mix pleroma.emoji gen-pack PACK-URL
+
+ Creates a new manifest entry and a file list from the specified
+ remote pack file. Currently, only .zip archives are recognized
+ as remote pack files and packs are therefore assumed to be zip
+ archives. This command is intended to run interactively and will
+ first ask you some basic questions about the pack, then download
+ the remote file and generate an SHA256 checksum for it, then
+ generate an emoji file list for you.
+
+ The manifest entry will either be written to a newly created
+ `index.json` file or appended to the existing one, *replacing*
+ the old pack with the same name if it was in the file previously.
+
+ The file list will be written to the file specified previously,
+ *replacing* that file. You _should_ check that the file list doesn't
+ contain anything you don't need in the pack, that is, anything that is
+ not an emoji (the whole pack is downloaded, but only emoji files
+ are extracted).
