+Actions for managing `.rel` files.
+
+### enemy_line line__ file
+
+The file at path `./enemy_line/line__.bin` is an obfuscated `.rel.lz` file that contains a sizeable chunk of game data. The game does a few things to hide the nature of the file.
+
+#### Decrypt line__.bin
+
+To decrypt the file.
+
+```shell
+# Decrypt file at path to *.rel.lz and *.rel
+gfz.exe rel-decrypt-line__ in/enemy_line/line__.bin
+```
+
+You must specify the region and serialization formats as they differ between regions.
+
+```shell
+# The default region information and search "*line__.bin"
+gfz.exe rel-decrypt-line__ in/ -search-subdirs --region j
+```
+
+Right now only GX is supported. AX stores the data elsewhere.
