| * jam.c - make redux |

| * See Jam.html for usage information. |
| * |
| * These comments document the code. |
| * |
| * The top half of the code is structured such: |
| * |
| * jam |
| * / | \ |

| * jamgram option \ |

| * builtins timestamp command execute |
| * | |
| * | |
| * | |
| * filesys |
| * |
| * |
| * The support routines are called by all of the above, but themselves |
| * are layered thus: |
| * |
| * variable|expand |
| * / | | | |
| * / | | | |
| * / | | | |
| * lists | | pathsys |
| * \ | | |
| * \ | | |
| * \ | | |
| * newstr | |
| * \ | |
| * \ | |
| * \ | |
| * hash |
| * |
| * Roughly, the modules are: |
| * |
| * builtins.c - jam's built-in rules |
| * command.c - maintain lists of commands |
| * compile.c - compile parsed jam statements |
| * execunix.c - execute a shell script on UNIX |
| * execvms.c - execute a shell script, ala VMS |
| * expand.c - expand a buffer, given variable values |
| * file*.c - scan directories and archives on * |
| * hash.c - simple in-memory hashing routines |
| * hdrmacro.c - handle header file parsing for filename macro definitions |
| * headers.c - handle #includes in source files |
| * jambase.c - compilable copy of Jambase |
| * jamgram.y - jam grammar |
| * lists.c - maintain lists of strings |
| * make.c - bring a target up to date, once rules are in place |
| * make1.c - execute command to bring targets up to date |
| * newstr.c - string manipulation routines |
| * option.c - command line option processing |
| * parse.c - make and destroy parse trees as driven by the parser |
| * path*.c - manipulate file names on * |
| * hash.c - simple in-memory hashing routines |
| * regexp.c - Henry Spencer's regexp |
| * rules.c - access to RULEs, TARGETs, and ACTIONs |
| * scan.c - the jam yacc scanner |
| * search.c - find a target along $(SEARCH) or $(LOCATE) |
| * timestamp.c - get the timestamp of a file or archive member |
| * variable.c - handle jam multi-element variables |
| * |
| * 05/04/94 (seiwald) - async multiprocess (-j) support |
| * 02/08/95 (seiwald) - -n implies -d2. |
| * 02/22/95 (seiwald) - -v for version info. |
| * 09/11/00 (seiwald) - PATCHLEVEL folded into VERSION. |
| * 01/10/01 (seiwald) - pathsys.h split from filesys.h |
