## 1.13 Jonathan Flynn
# Added GMT date qualifier.
## 1.12 Akim Demaille
# Cleaned up some of the Strong_comment in order to have a better
# support of --strip-level=1
## 1.11 Akim Demaille
# Handle `From: "Foo Bar" <my@email>'
## 1.10 Akim Demaille
# Aligned to 4.9.10 (order of sequences)
## 1.9 Akim Demaille
# Added Resent-*, and Precedence.
## 1.8 Akim Demaille
# Improved the author's tag
style "Mail Folder" is
written by "Akim Demaille <akim@freefriends.org>"
version is 1.14
requires a2ps version 4.12a
documentation is
"To use from elm and others, it is better to specify samp(-g -Email)samp,"
"since the file sent to printer is no longer truly a mail folder."
"This style also suits to news. samp(--strip)samp options are also useful"
"(they strip \"useless\" headers)."
""
"Whenever the changes of encoding are clear, a2ps sets itself the"
"encoding for the parts concerned."
""
"Tag 1 is the subject, and Tag 2 the author of the mail/news."
""
"Note: This style sheet is _very_ difficult to write. Please don't"
"report behavior you don't like. Just send me improvements,"
"or write a Bison parser for mails."

"ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz:_-"
