# Usage: depend -p package[-module] file1 [file2...]

#-----------------------------------------------------------------------------

# depend produces a list of dependencies of AIPS++ classes with respect to

# their included header files.  It produces a "$PACKAGE.time" file for the

# package which may be used to determine which C++ header and implementation

# files need to be processed to bring the "$PACKAGE.list" dependency list up

# to date.  These files are kept in $ARCHAUXD.

#

# depend is normally invoked by the "implement" makefile as part of the

# process of updating the makefile's included files.  The list of files passed

# to depend in that case consists of all ".cc" and ".h" files newer than the

# ".time" timestamp file produced by depend.  Invoking depend manually with an

# incomplete list of files could invalidate the dependency analysis.

#

# The C++ header and implementation files may be specified in full or in

# brief, for example, in full:

#

#     /aips++/code/aips/implement/Foo.cc

#     /aips++/code/aips/implement/Foo.h

#     /aips++/code/include/aips/Foo.cc

#     /aips++/code/include/aips/Foo.h

#

#     /aips++/code/aips/implement/module/Bar.cc

#     /aips++/code/aips/implement/module/Bar.h

#     /aips++/code/include/aips/module/Bar.cc

#     /aips++/code/include/aips/module/Bar.h

#

# or in brief:

#

#     Foo.cc

#     aips/Foo.h

#

#     module/Bar.cc
