#include "usage_compressed.h"
/* "Do not compress usage text if uncompressed text is small
* and we don't include bunzip2 code for other reasons"
*
* Useful for mass one-applet rebuild (bunzip2 code is ~2.7k).
*
* Unlike BUNZIP2, if FEATURE_SEAMLESS_BZ2 is on, bunzip2 code is built but
* still may be unused if none of the selected applets calls open_zipped()
* or its friends; we test for (FEATURE_SEAMLESS_BZ2 && <APPLET>) instead.
* For example, only if TAR and FEATURE_SEAMLESS_BZ2 are both selected,
* then bunzip2 code will be linked in anyway, and disabling help compression
* would be not optimal:
