Installed-binaries: list of binaries installed by this package I am establishing a new convention for all FreeCalypso tools, across different packages and source repositories: each FC tools package will have a file name Installed-binaries listing all user-invokable binaries that package installs in /opt/freecalypso/bin. These files are to serve as an aid to users and distro package maintainers who prefer to not add /opt/freecalypso/bin to their PATH. The alternative to adding this directory to PATH is to create a symlink for every installed binary in some standard location such as /usr/bin or /usr/local/bin, pointing to the actual binary in /opt/freecalypso/bin; having a list of all FC-installed binaries in a standardized format will allow this process to be automated.
