+*pi_spec.txt*   For Vim version 7.0aa.  Last change: 2002 Oct 29

+by Gustavo Niemeyer ~
+
+This is a filetype plugin to work with rpm spec files.
+
+Currently, this Vim plugin allows you to easily update the %changelog
+section in RPM spec files. It will even create a section for you if it
+doesn't exist yet. If you've already inserted an entry today, it will
+give you the opportunity to just add a new item in today's entry. If you
+don't provide a format string (|spec_chglog_format|), it'll ask you an
+email address and build a format string by itself.

+2. Customizing		|spec-customizing|
+
+==============================================================================
+1. How to use it				*spec-how-to-use-it*
+
+The spec_chglog plugin provides a map like the following:
+
+	:map <buffer> <LocalLeader>c <Plug>SpecChangelog
+
+It means that you may run the plugin inside a spec file by pressing
+your maplocalleader key (default is '\') plus 'c'. If you do not have
+|spec_chglog_format| set, the plugin will ask you for an email address
+to use in this edit session.
+
+Everytime you run the plugin, it will check to see if the last entry
+in the changelog has been written today and by you. If it's the entry
+mathes, it will just insert a new changelog item, otherwise it will
+create a new changelog entry. If you are running with
+|spec_chglog_release_info| enabled, it will also check if the name, version
+and release matches. The plugin is smart enough to ask you if it should
+update the package release, if you have not done so.
+
+Setting a map					*spec-setting-a-map*
+-------------
+
+As you should know, you can easily set a map to access any Vim command (or
+anything, for that matter). If you don't like the default map of
+<LocalLeader>c, you may just set up your own key. The following line
+shows you how you could do this in your .vimrc file, mapping the plugin to
+the <F5> key:
+
+	au FileType spec map <buffer> <F5> <Plug>SpecChangelog
+
+Note: the plugin will respect your desire to change the default mapping
+      and won't set it.
+
+This command will add a map only in the spec file buffers.
+
+
+==============================================================================
+2. Customizing					*spec-customizing*
+
+The format string				*spec_chglog_format*
+-----------------
+
+You can easily customize how your spec file entry will look like. To do
+this just set the variable "spec_chglog_format" in your .vimrc file like
+this: >
+
+	let spec_chglog_format = "%a %b %d %Y My Name <my@email.com>"
+
+Note that "%a %b %d %Y" is the most used time format. If you don't provide
+a format string, when you run the SpecChangelog command for the first
+time, it will ask you an email address and build the |spec_chglog_format|
+variable for you. This way, you will only need to provide your email
+address once.
+
+To discover which format options you can use, take a look at the strftime()
+function man page.
+
+Where to insert new items			*spec_chglog_prepend*
+-------------------------
+
+The plugin will usually insert new %changelog entry items (note that it's
+not the entry itself) after the existing ones. If you set the
+spec_chglog_prepend variable >
+
+	let spec_chglog_prepend = 1
+
+it will insert new items before the existing ones.
+
+Inserting release info				*spec_chglog_release_info*
+----------------------
+
+If you want, the plugin may automatically insert release information
+on each changelog entry. One advantage of turning this feature on is
+that it may control if the release has been updated after the last
+change in the package or not. If you have not updated the package
+version or release, it will ask you if it should update the package
+release for you. To turn this feature on, just insert the following
+code in your .vimrc: >
+
+	let spec_chglog_release_info = 1
+
+Then, the first item in your changelog entry will be something like: >
+
+	+ name-1.0-1cl
+
+If you don't like the release updating feature and don't want to answer
+"No" each time it detects an old release, you may disable it with >
+
+	let spec_chglog_never_increase_release = 1
+
+
+Good luck!!
