(include ⟨string1⟩ ⟨string2⟩ …) ¶(include-ci ⟨string1⟩ ⟨string2⟩ …) ¶Semantics: Both include and include-ci take one or more
filenames expressed as string literals, apply an implementation-specific
algorithm to find corresponding files, read the contents of the files in
the specified order as if by repeated applications of read, and
effectively replace the include or include-ci expression
with a begin expression containing what was read from the files.
The difference between the two is that include-ci reads each file
as if it began with the #!fold-case directive, while include
does not.
Note: Implementations are encouraged to search for files in the directory which contains the including file, and to provide a way for users to specify other directories to search.
