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.
