  * Implement shell style match patterns with fnmatch().
  * Make -f flag to overwrite files when installing, and to ignore
    files with wrong checksum or unexistent when removing.
+ * Add a target to check pkg integrity: normal files, metadata
+   and its dependencies.
 
 libxbps:
  * Fix glibc updates: removing libc is bad.
  * When accessing .plist files, only internalize_from_file once to
    avoid multiple open(3) and fstat(3) calls. [IN PROGRESS]
+ * Create xbps_upgrade_pkg() to replace or remove/unpack and register.
+   Remove duplicate code from xbps-bin/install.c. [IN PROGRESS]
+ * Add support to upgrade packages but overwritting current files;
+   this will fix libc, sh and others. An "essential" boolean obj
+   seems to be a good way to find such packages, like dpkg. [IN PROGRESS]
 
 xbps-repo:
  * Add support for remote repositories, requires libfetch.
