You can:

include the path where the reader resides in you PATH-variable;

create a symbolic link in a directory which is already in the PATH, like /usr/local/bin;

create an alias in the shell to expand a name to the fully qualified pathname

write a wrapper-script, which calls the reader itself and which knows it absolute pathname, then put the wrapper-script in a directory included in PATH.

And some more possibilities. Haven't i got your question right or was that really your problem?
