krb5-config tells the application programmer what special flags to use to compile and link programs against the libraries installed by Heimdal.
Print the prefix if no dir is specified, otherwise set prefix to dir.
Print the exec-prefix if no dir is specified, otherwise set exec-prefix to dir.
Output the set of libraries that should be linked against. This also includes rpath flags with the expectation that the C compiler is used for final link-edits.
Output the set of flags to give to the C compiler when using the Heimdal libraries.
By default krb5-config will output the set of flags and libraries to be used by a normal program using the krb5 API. The user can also supply a library to be used, the supported ones are:
use the krb5 gssapi mechanism
use the client-side kadmin libraries
use the server-side kadmin libraries
krb5-config appeared in Heimdal 0.3d.
