as we are storing the help text which is a string in a variable,so this
string will be embedded in the compiled shared object(.so) files.So,this
string will always get loaded whenever the plugin will be loaded.As the
string may be of any length so if 100 plugins are loaded at the same time
then loading of 100 help strings may cause performance issues and if user
don't need the help manual then efforts to load help string will go
waste.Al once told me that "You pay only for what you use" so I think
loading the strings with the plugin should not be preferred.Correct me If I
am wrong or if I misunderstood something.
