    As ST/X is (still) very tightly bound with stc, we keep the package and project information

    in a class-object (instead of some project object) and all queries about package contents and 

    attributes are implemented as class methods. 

    This has the advantage, that it can be compiled and included in a compiled class library just like any other class.

    Every package includes a subclass of me (an instance of my meta), which provides useful

    information about the versioning and packaging. 

    Me myself, I know how to generate dependency information and can generate makefiles and other build-support 

    files for compilation (see the browser's 'Checkin Build Support File' menu item. For more details, see

    section 'Build Support Files' below.

    When a package is loaded from a binary shared class lib (i.e. a compiled class library is loaded

    via 'Smalltalk loadPackage:'), the loading is done in multiple phases:

        1) the shared object is loaded, but not installed (registered) in Smalltalk

        2) the ProjectDefinition class is registered and initialized.

        3) the ProjectDefinition class is asked to load its prerequisites. This may lead to other packages

           to be loaded - either as binary class libraries or from source, whichever is found.

        4) the remaining classes and extensions are registered

    ## Some special notes about extension methods:

      if a package is loaded (Smalltalk loadPackage:'foo:bar/baz'), any already loaded package of which

      methods are overwritten by an extension method of the loaded package, the other package is asked to safe those

      methods in its safe(ForOverwrittenMethods). 

      Thus, if the other package or any of its classes is asked

      to file itself out, it can do so using the safe (otherwise, you'd not be able to check the original class into

      its repository while it has an overriding extension loaded).

      Also, the information about which other package was in charge when a method is overwritten is recorded in

      extensionOverwriteInfo. 

      This is used to correctly reinstall an overwritten method, whenever a package is unloaded.

    ## Custom project definition methods

    Some packages may want to compile custom methods when project definition is updated

    based on project contents - similarly to how #classNamesAndAttributes or #extensionMethodNames

    are updated.

    To support this, packages mey add extension methods annotated by <method:category:overwrite:>

    or <method:category:>. The meaning og arguments is the following:

    * method: <Symbol>     - the selector of method which this method generates.

    * category: <Symbol>   - the category in which to place generated method

    * overwrite: <Boolean> - specifies whether the method should obe overwritten

                             or not. Use `false` only for methods which should be

                             generated once and then left for user to manually tweak.

                             optional, defaults to `true` (i.e., do owerwrite methods)

    The annotated method is invoked to get the code od the method to generate, i.e., it must

    return the source code as String. If it returns nil - no method is generated.

    ## Build Support Files

    To support pre-compilation of a package, ProjectDefinition can generate a set of makefiles and other

    support files to allow that. To see the set of files that should be generated, see #fileNamesToGenerate.

    These files are usually generated and saved to the repository upon a commit - the source code management

    does (should) care for this.

    Packages may add more files to this list by defining an (extension) mehtod in project definition class

    and by annotating the method by <file:overwrite:> annotation:

        * the first parameter is the file name to generate as String, relative to the package root. As directory

          separator, use slash (as on UNIX), it will be automagically converted to platform's separator.

        * The second paramterer (true or false) tells the SCM whether the file should be generated (and thus

          overwritten) upon each commit (when true) or only the first time (when false). Important: see the 

          emark below.

        * The method itself should return file's contents a string. If it returns nil, then the file is *not*

          generated at all.

    For examples, see #generate_java_build_auto_dot_xml and #generate_java_build_dot_xml defined by STX:LIBJAVA.

    REMARK: CAUTION:

    The overwrite: boolean is currently *not* supported by old SCM managers, more specifically

    CVSSourceCodeManager does not support it. CVSSourceCodeManager will always overwrite the file!!

    It *is* supported by all SCMs based on new stx:libscm. More specifically, *it is supported* by

    Mercurial.

    ## Adding additional rules to generated makefiles

    There are two ways to add additional rules to generatec makefiles (Make.proto and bc.mak):

      1) overriding #additionalRules_make_dot_proto and/or #additionalRules_bc_dot_mak

      2) addng a method annotated by <file:target:> or <file:target:extends:> 

    ### Overriding #additionalRules* methods

    You may override #additionalRules_make_dot_proto and/or #additionalRules_bc_dot_mak and return

    string containing the code of the rules. This string is inserted to the resulting makefile

    as-is. This is the traditional way of doing this.

    If you any of the targets defined there to be called as part of standard build, you may

    also want to list these targets in #additionalTargets_make_dot_proto and/or

    #additionalTargets_bc_dot_mak

    ### Adding annotatated method

    Alternatively, you may add one method per rule and annotate it by

    <file:target:> or <file:target:extends:> annotation. For example,

    to call ant whenever a package is built, add a method like:

    additionalRuleAnt_make_dot_proto

        <file: 'Make.proto' target: 'ant' extends: 'pre_objs' >  

        ^ '

        java:

                ant -f java/build.xml

        '

    The meaning annotation parameters is the following:

        * file: <String> - name of the file in which to include

          the rule. Currently only two values are valid:

          'Make.proto' and 'bc.mak'.

        * target: <String> - name of the target'

        * extends: <String> - optional name of the target that this additional

          rule extends. This means that the extending target (specified by target:

          annotation parameter) is called as part of building of  the extended target

          (i.e., the target specified by extends: annotation parameter). Not all targets

          are extendable, see below.

    Method annotated by these annotations should return - when executed - a string

    with exactly one rule. The rule name SHOULD match with the name in target: annotation

    parameter, otherwise the extends: parameter will not work correctly.

    If the methor returns nil, the rule is not included in resulting makefile.

    The advantage of this approach is that it allows for additional, non-basic packages to hook in

    and add their own targets if they want to. The disadvantage is that if package makefiles

    are regenerated without this extending package loaded, targets are lost. To avid this,

    you may want to add this non-basic package to prerequsites.

    Currently, this mechanism is used by STX:LIBJAVA to call ant to compile package's java classes.

    #### Extendable targets

    Make.proto:

        all

        clean

        ...more to be added...

    bc.mak

        ALL

        clean

        ...more to be added...
