       headache - A program to manage the license of your source file.


       headache [-h file] [-c file] [-r] [-help | --help] file...


       This manual page documents briefly the headache command.

       This manual page was written for the Debian GNU/Linux distribution
       because the original program does not have a manual page.

       It is a common usage to put at the beginning of source code files a
       short header giving, for instance, some copyright informations.
       headache is a simple and lightweight tool for managing easily these
       headers. Among its functionalities, one may mention:

       ·   Headers must generally be generated as comments in source code
           files.  headache deals with different files types and generates for
           each of them headers in an appropriate format.

       ·   Headers automatically detects existing headers and removes them.
           Thus, you can use it to update headers in a set of files.


           Name of one file to process

       -h file
           Create a header with text coming from file

       -c file
           Read the given configuration file

       -help, --help

       Let us illustrate the use of this tool with a small example. Assume you
       have a small project mixing C and Caml code consisting in three files
       'foo.c', '' and 'bar.mli'', and you want to equip them with some
       header. First of all, write a header file, i.e. a plain text file
       including the information headers must mention. An example of such a
       file is given in figure 1. In the following, we assume this file is
       named 'myheader' and is in the same directory as source files.

       Then, in order to generate headers, just run the command : headache -h
       myheader foo.c bar.mli

       Each file is equipped with an header including the text given in the
       header file 'myheader', surrounded by some extra characters depending
       on its format making it a comment (e.g. '(*' and '*)' in '.ml' files).
       If you update informations in the header file 'myheader', you simply
       need to re-run the above command to update headers in source code
       files: existing ones are automatically removed.

       Similarly, running : headache -r foo.c bar.mli removes any
       existing in files 'foo.c', '' and 'bar.mli'. Files which do not
       have a header are kept unchanged.


       File types and format of header may be specified by a configuration
       file. By default, the default builtin configuration file given in
       figure 2 is used. You can also use your own configuration file thanks
       to the -c option : headache -c myconfig -h myheader foo.c

       In order to write your own configuration, you can follow the example
       given in figure 2. A configuration file consists in a list of entries
       separated by the character '|'. Each of them is made of two parts
       separated by an '->'.

       The first one is a regular expression. (Regular expression are enclosed
       within double quotes and have the same syntax as in Gnu Emacs.)
       headache determines file types according to file basenames; thus, each
       file is dealt with using the first line its name matches.

       The second one describes the format of headers for files of this type.
       It consists of the name of a model (e.g. 'frame'), possibly followed by
       a list of arguments. Arguments are named: 'open:"(*"' means that the
       value of the argument 'open' is '(*'.  headache currently supports
       three models and a special keyword:

           With this model, headers are generated in a frame. This model
           requires three arguments: 'open' and 'close' (the opening and
           closing sequences for comments) and 'line' (the character used to
           make the horizontal lines of the frame). Two optional arguments may
           be used 'margin' (a string printed between the left and right side
           of the frame and the border, by default two spaces) and 'width'
           (the width of the inside of the frame, default is 68).

           Headers are typeset between two lines. Three arguments must be
           provided: 'open' and 'close' (the opening and closing sequences for
           comments), 'line' (the character used to make the horizontal
           lines). Three optional arguments are allowed: 'begin' (a string
           typeset at the beginning of each line, by default two spaces),
           'last' (a string typeset at the beginning of the last line) and
           'width' (the width of the lines, default is 70).

           This model generates no header and has no argument.

           Skip line corresponding to one of the "match" parameters regexp.
           For this kind of line, every first part pattern that matches the
           file basename is taken into account.
