+Gender-specific strings
+-----------------------
+Some in-game strings are able to have different variants based on the player character's pronouns. For example, `AA_CUBE_POST_BATTLE_MEREDITH3` has three variants:
+
+* `AA_CUBE_POST_BATTLE_MEREDITH3.f` (if player has she/her pronouns)
+* `AA_CUBE_POST_BATTLE_MEREDITH3.m` (if player has he/him pronouns)
+* `AA_CUBE_POST_BATTLE_MEREDITH3.n` (if player has they/them pronouns)
+
+This script is able to automatically detect strings that have gender-variants, and will include all three versions of the string in the output csv.
