To avoid having to specify each spec by hand (which can miss specs to be
added), the test infrastructure now performs classpath discovery so that
each spec added, is automatically considered.

----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctions]
----
The list of functions returned can be customized based on the pattern.
It can be an exact match:
["source","sql",subs="attributes,callouts,macros"]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctionsLikeExact]
----
A wildcard for exactly one character:
["source","sql",subs="attributes,callouts,macros"]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctionsLikeChar]
----
A wildcard matching zero or more characters:
["source","sql",subs="attributes,callouts,macros"]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctionsLikeWildcard]
----
Or of course, a variation of the above:
["source","sql",subs="attributes,callouts,macros"]
----
include-tagged::{sql-specs}/docs/docs.csv-spec[showFunctionsWithPattern]
