In 1.52, the synopsis lines read as such: webapp-config [--bug-report] -I [-dghusDE --soft --copy --secure] {app-name} {app-version} webapp-config [--bug-report] -U [-dghusDE] {app-name} {app-version} webapp-config [--bug-report] -C {-d directory} This leads the user to believe that the --copy/secure/soft flags only apply to the -I operation when in fact, they also work with -U. Additionnally, the --secure flag *must* be used with -C when cleaning up an installed made with --secure. Lastly, the -C operation also requires the {app-name} and {app-version} information.
The man page has been edited and the changes will be included in the next release of webapp-config.
