 +To use ''auc'' to check for new packages, or newer versions of the current branch, simply use the ''-c'' option.  This is completely benign, as ''auc'' terminates after reporting what it sees without doing anything further.  Using ''-c'' to experiment with the other options is a safe way to explore how ''auc'' works.

 +$ auc -c
 +auc/0.3.2-1

 +By default, ''auc'' works on the branch currently installed on your device.  The ''-b'' option can be used to change this behavior, so that you can upgrade or downgrade between release branches (like ''19.07'' or ''23.05'') or snapshot (where you just literally use ''snapshot'' as the value).  The ''-B'' option can be used to select a specific version within a branch, such as ''22.03.1'' or ''23.05.0''.
 +
 +This example detects that 23.05.2 is installed, and shows information related to downgrading to 22.03.4.
 +As indicated by the warning, this is probably not a good idea as the jump in versions is "too far", but you *can* use ''-B'' to downgrade within a branch pretty safely.
 +<code bash>
 +$ auc -c -b 22.03 -B 22.03.4
 +auc/0.3.2-1
