 Tasks:
 
-  * See if ob-installdocs can/should handle non-directory non-regular files.
-  * Review "IFS=... cmd ..." commands.
-  * Review eval commands.
+  * Rewrite cache file handling.
+    - Make a new library module with the following functions:
+      * ob_init_cache file
+      * ob_read_cache
+      * ob_set_cache_var name value
+    - Use ob_set_cache_var in _ob_set_{source,binary}_parameter.
+    - Remove code to read cache file from ob_parse_package_metadata.
+    - Remove code to write cache file from ob_parse_package_metadata.
+    - TODO: Should ob_{init,read}_cache ever be called automatically?
+      * If not, `ob_parse_package_metadata -c FILE` could be:
+        - `ob_init_cache_file FILE; ob_read_cache || ob_parse_package_metadata`
+  * Fix ob-applypatches to not fall over when it runs too much.
+    - Current behavior: "I've been here already!  What do?  *trip*"
+    - Track applied patches in ob-applypatches.
+      * Use ob_set_cache_var to cache the list of patches.
+  * General code auditing and cleanup:
+    - Switch to using printf (safer and more portable than echo) for everything.
+    - Protect against command operands beginning with "-", e.g.:
+      * `[ "x${foo}" = 'xbar' ]` instead of `[ "${foo}" = 'bar' ]`
+      * `mkdir -p -- "${foo}"` instead of `mkdir -p "${foo}"`
+    - Add more error handling.
+    - Review "IFS=... cmd ..." commands.
+      * "IFS=... read" is fine.
+    - Review eval commands.
   * Finish ob-checkbuilddeps.
   * Write ob-genchanges.
+  * See if ob-installdocs can/should handle non-directory non-regular files.
   * Write manual pages for functions and utilities.
   * Support package signing (requires opkg to be built with GnuPG and GPGME).
