46: # It is designed to work cleanly and independently from pre-existing
47: # directory trees such as /usr/src/redhat/*.
48:
49: # I still need to implement the CONFIGURATION_FILES and

51: # script.
52:
53: # Take in a file list (from standard input),
54: # a description tag and version tag from command line argument
55: # and temporarily generate a:
56: # RPM .spec file
57: # RPM Makefile
58: # SourceRoot
59:
60: # A resulting .rpm file is generated.

106: Usage: <TAG> <VERSION> [CONFIGURATION_FILES]
107: [DOCUMENTATION_FILES] [PATHPREFIX] [CUSTOMIZATION_XML]
108: Standard input provides the list of files to work with.
109: TAG, required descriptive tag. For example, a kerberos software
110: package might be tagged as "krb4".
111: VERSION, required version. Needed to generate version information
112: for the RPM. This should be in the format N.M where N and M are
113: integers.
114: CONFIGURATION_FILES, optional comma-separated listing of files to
115: be treated as configuration files by RPM (and thus subject to saving
116: during RPM upgrades).
117: DOCUMENTATION_FILES, optional comma-separated listing of files to be
118: treated as documentation files by RPM (and thus subject to being
119: placed in the /usr/doc/RPM-NAME directory during RPM installation).
120: PATHPREFIX, optional path to be removed from file listing. This
121: is in case you are building an RPM from files elsewhere than
122: root-level. Note, this still depends on a root directory hierarchy
123: after PATHPREFIX.
124: CUSTOMIZATION_XML, allows for customizing various pieces of information such
125: as vendor, summary, name, copyright, group, autoreqprov, requires, prereq,
126: description, and pre-installation scripts (see more in the POD;
127: perldoc make_rpml.pl).

406: =head1 NAME
407:
408: make_rpm.pl - automatically generate an RPM software package
409:
410: =head1 SYNOPSIS
411:
412: Usage: <TAG> <VERSION> [CONFIGURATION_FILES]
413: [DOCUMENTATION_FILES] [PATHPREFIX] [CUSTOMIZATION_XML]
414:
415: Standard input provides the list of files to work with.
416:
417: TAG, required descriptive tag. For example, a kerberos software
418: package might be tagged as "krb4".
419:
420: VERSION, required version. Needed to generate version information
421: for the RPM. This should be in the format N.M where N and M are
422: integers.
423:
424: CONFIGURATION_FILES, optional comma-separated listing of files to
425: be treated as configuration files by RPM (and thus subject to saving
426: during RPM upgrades).
427:
428: DOCUMENTATION_FILES, optional comma-separated listing of files to be
429: treated as documentation files by RPM (and thus subject to being
430: placed in the /usr/doc/RPM-NAME directory during RPM installation).
431:
432: PATHPREFIX, optional path to be removed from file listing. This
433: is in case you are building an RPM from files elsewhere than
434: root-level. Note, this still depends on a root directory hierarchy
435: after PATHPREFIX.
436:
437: CUSTOMIZATION_XML, allows for customizing various pieces of information such
438: as vendor, summary, name, copyright, group, autoreqprov, requires, prereq,
439: description, and pre-installation scripts (see more in the POD;
440: perldoc make_rpml.pl).
441:
442: Examples:
443:
444: [prompt] find notreallyrootdir | perl make_rpm.pl makemoney 3.1 '' \
445: '/usr/doc/man/man3/makemoney.3' notreallyrootdir
446: would generate makemoney-3.1-1.i386.rpm
447:
448: [prompt] find /usr/local/bin | perl make_rpm.pl mybinfiles 1.0
449: would generate mybinfiles-1.0-1.i386.rpm
450:
451: [prompt] find romeo | perl make_rpm.pl romeo 1.0 '' '' '' customize.xml
452: would generate romeo with customizations from customize.xml.
453:
454: The CUSTOMIZATION_XML argument represents a way to customize the
455: numerous variables associated with RPMs. This argument represents
456: a file name. (Parsing is done in an unsophisticated fashion using
457: regular expressions.) Here are example contents of such a file:

506: =head1 DESCRIPTION
507:
508: Automatically generate an RPM software package from a list of files.
509:
510: This script builds the RPM in a very clean and configurable fashion.
511: (Finally! Making RPMs the simple way!)
512:
513: This script generates and then deletes temporary
514: files (and binary root directory tree) to build an RPM with.
515: It is designed to work cleanly and independently from pre-existing
516: directory trees such as /usr/src/redhat/*.
517:
518: Take in a file list (from standard input),
519: a description tag and version tag from command line argument
520: and temporarily generate a:
521: RPM .spec file
522: RPM Makefile
523: SourceRoot
524:
525: A resulting .rpm file is generated.
