X                README FILE FOR CPR
X                ^^^^^^^^^^^^^^^^^^^
X
XOK, we gotta have a README file, so you can tell what this does and
Xwhere it came from.  Well, I pulled it off the net myself early this
Xyear (1989), and found it sort of useful.  It's a pretty-printer for
XC programs.
X
XWHAT IT DOES:
X   -    Paginates, with meaningful page headers.
X   -    Makes a table of contents for files and functions.
X   -    Won't start a function at the bottom of a page.  (In fact,
X        has an option to print only one function per page.)
X
XWHAT IT DOESN'T DO:
X   -    Indent.
X   -    Put brackets on separate lines.
X   -    Other stuff that "C beautifiers" do.
X
XWhen I inherited a couple of pretty big C programs to maintain, the
Xfirst thing I did was to try to get a bunch of listings with CPR.  I
Xfound that CPR as I received it wasn't up to the job.  It certainly
Xwas after I added a few enhancements.  Here's the enhanced version,
Xcast back upon the waters of the net.  The enhancements are:
X
X   -    Any arguments can appear in a file rather than on the command
X        line, and in pretty free form.  (As received, you could only have
X        filename arguments in a file, one name per line.)
X   -    The table of contents can contain a single sorted index of
X        all functions across all files.
X   -    The option "-?" will give a help screen for the options
X        (more like the PC idiom than the usual UNIX utility).
X   -    Lines can be "intelligently" folded if they go beyond the
X        width of a page.  (You wouldn't believe this program I
X        inherited, and its 160-column lines.)
X
XThis remains public domain, which is as I found it.  (It's free, and
Xworth every penny  :-)

X/*    CPR   -   Pretty-Printer for C programs
X *
X *    This program prints the files named in its argument list, preceding
X *    the output with a table of contents. Each file is assumed to be C
X *    source code (but doesn't have to be) in that the program searches
X *    for the beginning and end of functions. Function names are added to
X *    the table of contents, provided the name starts at the beginning of
X *    a line. The function name in the output is double striken.
X *
X *    PAGE SIZE
X *    The option "-l" indicates that the following argument is to be
X *    the page length used for output (changing the page length hasn't been
X *    tested much).
X *    The option "-w" indicates that the following argument is to be
X *    the page width (and lines are folded to that width, using a
X *    reasonably aesthetic folding algorithm).  The default, in the
X *    absence of "-w" is not to fold lines.
X *
X *    NUMBERING OF LINES & PAGES
X *    The option "-n" indicates that output lines should be numbered with
X *    the corresponding line number from the input file.
X *    The option "-N" indicates that page numbers start at 1 within each
X *    file.
X *
X *    FORMATTING THE PROGRAM
X *    The option "-p" indicates what proportion of the page in steps of 16
X *    should be used for deciding if a new function needs a new page.
X *    That is -p12 (the default) indicates that if a function starts
X *    within the top 12/16 (3/4) of the page then do it, otherwise put it
X *    on a new page.  Thus the higher the number (upto 16) the closer to
X *    the bottom of the page will functions be started. -p0 says put each
X *    func on a new page.
X *
X *    By default blank space is inserted after every closing '}'
X *    character. Thus functions and structure declarations are nicely
X *    isolated in the output. The only drawback to this is that structure
X *    initialization tables sometimes produce lots of white space.
X *    The "-r" option removes this space, or changes it to the indicated
X *    length.
X *
X *    TABLE OF CONTENTS OPTIONS
X *    The option "-s" indicates that the table of contents should be sorted
X *    by function name within each file.
X *    The option "-S" also calls for a sorted table of contents, but with
X *    a case-insensitive sort.
X *    The option "-x" indicates that the table of contents should include
X *    a sorted index of functions across all files.
X *    The option "-X" also calls for a sorted index of functions, but with
X *    a case-insensitive sort.
X *
X *    The option "-C" indicates that ONLY the table of contents is to
X *    be printed, not the source files themselves.
X *
X *    The option "-c" indicates that only files with the extension ".c"
X *    should be examined for files to list in the table of contents.
X *
X *    The option "-T" indicates that the following argument is a file
X *    name; the contents of that file is to be printed verbatim in the
X *    output before the table of contents, as a Title Paragraph.
X *
X *    MISCELLANEOUS OPTIONS
X *    The option "-?" indicates that a help screen for CPR be sent
X *    to stderr (generally the screen), but no processing done.
X *    The help screen is more verbose than the usage message that's
X *    printed on error, and summarizes all options of CPR.
X *
X *    The option "-f" indicates that the following argument is a file
X *    name; the contents of that file are to be treated just as command
X *    line arguments.  (Thus you can, for example,  make a ".cprrc" file
X *    with the right options and source files, in each of your
X *    source directories.)
