+Scans the project (recursively) for matching files and writes a corresponding
+*.gen.go per file with helpers.
+

+- -m, --marshal   Generate JSON marshal/unmarshal methods
+- -s, --sql       Generate database/sql helpers (int, null types) (default: true)
+
+Behavior:
+- Always generates Names() and Values()
+- With --marshal: adds JSON encoding/decoding
+- With --flag: adds flag.Value support
+- With --sql: adds SQL driver, int, NullInt, NullString helpers
+
+Examples:
+  atomctl gen enum -m -s
+  atomctl gen enum --flag=false`,
