#5 2493 rmg Rewrite the past: update all jam's source with comments to
reflect changes since about 2.3, very early 2001.

Whitespace only change.

=== computer:1666: Change 37660 by seiwald@play-seiwald on 2002/11/06 22:41:35

Note: I regenerated jamgram.c on my linux 7.3 system prior to
the submit, since patch was so unhappy trying to lay down the
changes from Christopher's change. Presumably this is just due to
different yacc/bison/whatever particulars on the system where
Christopher made the changes originally. - rmg
#4 2491 rmg Some consting in jam to make it more compilable by C++ compilers.

No functional change.

=== computer:1666: Change 37433 by perforce@perforce on 2002/10/30 16:08:51

Recreational const-ing of jam, for compilers that don't allow
"string" to be passed as a non-const char *.

This included a few places where we were modifying what could
possibly have been read-only storage, oddly enough.

No functional change.

#3 2490 rmg Jam langauge work: make 'return' actually return from the rule,
rather than just setting the return value.  Introduce new
break/continue statements for managing loops.

User visible change to be documented in Jam.html.

=== computer:1666: Change 37200 by seiwald@play-seiwald on 2002/10/22 15:41:28

Gross rework of Jam.html documentation, including:

- the description of parameters for rules
- description of -g flag
- a new description of targets
- more about rules and their return values
- better separation of rules and updating actions
- putting borders around the tables

(Undocumented) change to documentation.

=== computer:1666: Change 37551 by seiwald@waffle-cyg-seiwald on 2002/11/03 23:17:12

Document jam's new and working break/continue/return statements.
