# usage: inclosure [ -I dir ] ... [ -G header-name ] ... header-name ...
|
|
#
|
|
# Locates each standard header and argument header-name in the
|
|
# specified "-I" include path (default is /usr/include) and parses
|
|
# any header names out of its #include directives. These names are
|
|
# treated recursively to identify a _transitive_closure_ of standard
|
|
# header names, which is sorted and sent to standard output. Headers
|
|
# not specified with -G, and included somewhere but not located are
|
|
# reported.
|
|
#
|
|
# Each header reported by this program must be "shadowed" by a
|
|
# file of the same name in a C++ header. See
|
|
# http://www.cantrip.org/cheaders.html
|
|
#
|
|
# BUGS:
|
|
# - Cannot cope with header file names that contain spaces
|
|
# - Ignores comment-block delimiters
|
|
# - Ignores sub-includes under #include_next headers.
