|
# Analyze a LaTeX logfile producing appropriate output on error and |
|
# returning a boolean to let the caller know if, in our opinion, it's |
|
# worth continuing on to produce the PDF file. |
|
# |
|
# Parameters: |
|
# logfilename - Name of the logfile. |
|
# texfile - Name of the LaTeX file that was being processed. |
|
# advanced_role - True if the user is privileged with respect to the printout |
|
# (e.g. is the course coordinator or some such thing). |
|
# Returns: |
|
# 1 - Caller is advised to continue to create the PDF. |
|
# 0 - Caller need not bother creating the PDF. |
|
# Side Effects: |
|
# Messages are printed to describe any errors that have been encountered. |
|
# NOTE: |
|
# The current policy is to assume that if LaTeX decided to insert some text |
|
# it has salvaged the resource and the resource can be printed.. in that case |
|
# a message is emitted from this sub. |
