BaseFileABFile generated using environment variables
This is the same kind of file as .in file for autoconf, except we use the variable definition of Buffer.add_substitute. This is the default file to be generated by configure step (even for autoconf, except that it produce a master file before).
The file must end with '.ab'.
val to_filename : OASISTypes.unix_filename -> OASISContext.source_filenameCompute the target filename of an .ab file.
val replace : ctxt:OASISContext.t -> OASISTypes.unix_filename list -> unitReplace variable in file %.ab to generate %.
